MUSINGS: On various characters in the audiophile hobby, debates, opinions and the Hearing Test.

Hey everyone, once awhile I'll take a look at stuff YouTube offers me in the feed that might be interesting. I see that in the last few months, there has been this channel called "The HiFi Five" and in Episode 6 (November 19, 2025) they invited Dennis Burger of SoundStage! for a discussion. I found this video actually quite interesting as an illustration of objective/subjective mindsets, biases, and the personality styles that come through in communicating such ideas.

Check this out if you have time for a deeper dive with discussion to follow, related to the contents and characters:

It looks like most episodes feature the 4 regulars + 1 guest. Of the four regulars, I don't really know who Ron Resnick is; I see he's the co-owner/admin of What's Best Forum which I've visited infrequently - clearly an ad-driven audiophile forum with many company-sponsored subfora. Inevitably, if there is investment from Industry, this will affect the tone and content of discussions among moderators and participants. Ron acts as the moderator for these videos. There's Danny Kaey who has been around for awhile, apparently these days representing EMM Labs and the YouTube channel Sonic Flare, but I remember when he gave a talk encouraging adoption of MQA at RMAF'2017. I trust we've all moved on from that nonsense. 😒

Then we have a couple of dealers/sellers Elliot Goldman of Bending Wave USA who sells high-end stuff, and Jay Caceres from Jay's Audio Lab channel who's also a representative of cables, power conditioner products, does consultations, and I guess sells various pre-owned stuff on his website. We've talked about Jay's opinions here over the years (here, here), and I see these days he's building his listening space out in Texas - hope the money invested into this works out for him in this economically volatile time.

Obviously, with the background of these four regular members, one should not be surprised to find viewpoints that would show stronger allegiance to the high-end Industry. If you've spent time with audiophiles of this variant, such as the local dealers or at audio shows talking to sales reps, you're probably going to find one or more of these ideas pop up during discussions and debates:

1. They generally claim that there are a number of unmeasurable audible sound system characteristics: typically things like subjective sound stage, depth, warmth, presence, PRaT, etc. cannot be quantified in their minds. (Obviously many of these are measurable even if they are composite properties of a number of tests as suggested by Dennis Burger when asked about measuring "depth of soundstage".)

2. Ergo, the only 'instrument' they trust that an audiophile needs for system evaluation is their ears. There's a tendency to disparage the use of instruments to measure sound even though it seems that many of them have no direct experience running measurements themselves to really make that statement based on fact.

3. The idea of the Industry or "heroes" of the industry selling snake oil is typically denied - because they claim to hear the differences of course, and that such devices affect the sound system outside the realm of typical physical measurement and analysis. The idea that the Industry might be dishonest in all kinds of ways I guess isn't something they want to openly entertain.

4. Common reasons given for others not hearing what they claim they hear include: others are not experienced enough, their systems are not good enough (often code for the system isn't expensive enough or using the 'best' favored hi-end brands).

5. When asked to discuss a claim that might seem unlikely, often these individuals will show superficial understanding of the science behind audio technologies, psychoacoustics, or I've come across ones who seem literally phobic of even talking about an explanatory model for what they believe!

6. When pressed further, you might see a defensive posture in these individuals as if they literally believe they possess "Golden Ears" and their experiences tower above all else with name-dropping of products they've owned and who they know in the industry over the years. As if mere opinions constitute truth.

7. Eventually they might want to claim that others have not "learned the difference between hearing and listening" - which they apparently have mastered in some way. This kind of implication might then get uncomfortable, and unnecessarily personal because apparently you are lacking this person's skills.

If you watch the video and have read some of my writings, I think you'll appreciate when I say that I'm impressed by Dennis Burger's rational stance on the questions (and challenging postures) he's presented by the others without getting overly defensive and sticking to his position when needed. Well done asking probing, respectful questions when given the opportunity. A wonderful demonstration of how to get the job done as an objective-leaning audiophile without letting immaturity devolve the debate into personal attacks! I love his comment about the irrationality of "audiophile" ethernet switches. (As usual, I'm sticking to the Bits Are Bits story when it comes to basically any half-decent digital gear these days including those switches. 😁)

I was positively surprised by Danny Kaey's position for much of this discussion and I think he's absolutely right that dealers believe in expensive products simply because they make money. Obviously a no-brainer that this is the most likely reason given the self-interest and desire to perpetuate beliefs that lead to sales. It was funny seeing him call Elliot "you're so full of s*it man, it's hilarious". Danny's repeated suggestion for a blind test is also nice to hear! Let's see if this happens in Jay's future sound room. And yes, well done multichannel is better than stereo; it's obvious. 🙂

Probably for most objectivists, the positions held by Jay and Elliot are the most unreasonable even if their positions are absolutely not surprising! I suspect in a heated debate, they would show most or all of those 7 points above that characterize what I see as an extreme, but common, form of audiophile subjectivism, especially when applied to snake oil. It does not help when Elliot states his opinion that "musicians generally and recording engineers are some of the worst hi-fi listeners that I have ever met" (and I guess Danny agrees). Hmmm guys, I really don't think this kind of gross generalization is helpful especially if we want musicians and engineers to do good work - if you can't be part of the solution, at least don't be part of the problem by creating divisions.

One is free to hold opinions and express whatever ideas (within legal boundaries), but it obviously does not look good when one holds on strongly to ideas without reasonable justification in a debate. To say that the discussion of something is "higher above my pay grade" (Jay) might sound honest, but not to show wiggle room or willingness to consider that one is perhaps wrong I don't think speaks well to the viewpoint or one's character. To imply that because a more-objective-leaning person has explanations for what they hear (or not hear) and being educated about the science blinds them to the truth (ie. a false-negative position that there's actually something to hear if they only had an open mind, is a rather anti-intellectually despicable assertion by Jay towards Dennis' position) doesn't work because it's still the objective-leaning folks who are consistently open-minded enough to embrace things like doing blind listening tests to seek answers using methods that control for biases. What kind of "honesty control" does Jay apply when making his listening claims about $100k this or that? The most likely explanation for why Jay hears the effects of speaker risers and stuff like his expensive Critical Mass speaker/component footers is that he wants to believe (like others who "talk their book") and probably would like to make a few bucks off this stuff selling his inventory.

By the way, Elliot claims "to say there is no art in audio... what I'm doing is art" seems silly. Sure, as a dealer, setting up a fancy sound room might include application of the art of interior decoration, but picking out a few components that perform well together at the customer's price point, placing the gear in more-than-likely pretty normal, typical stereo configurations likely with some trial-and-error to optimize sound at the main listening position while listening to music isn't exactly a high level art. The art is primarily in the music itself; the devices operate based on scientific principles, and the room set-up is also mostly explainable by science. While room set-up and component selection will incorporate personal preferences, I would not call making such choices an artistic endeavor.

Finally, it's great to see that Danny Kaey brought up his audiogram result at 17:20. Yeah, with the new AirPods Pro 2 and Pro 3, Apple has added a feature that allows you to measure your hearing threshold similar to the procedure used by an audiometrist. Years ago, I also raised the importance of something basic like the pure-tone audiogram as something that should be a pre-requisite for those who want to review gear and claim to have Golden Ears. This is especially true when we come across articles by older reviewers. If not an audiogram, maybe some kind of certification? 😉

Beyond the Apple ecosystem, if you're like me and use an Android phone primarily, there's also the app Hearing Test which I have found to be excellent! Check out their website. And they have some published journal articles using this app.

Since each headphone will have a different frequency response, calibration data is needed and it's great that many popular headphones have entries in the software's database. They recommend that for best results, use the Sennheiser HD 450BT or Soundcore Life Q30. I used my 1MORE SonoFlow which is a very reasonably priced, enjoyable Bluetooth headphone with LDAC support, and excellent battery life. For this test, I turned noise cancellation off (remove potential DSP effects), listening in my quiet sound room after work later one evening. Since auditory thresholds change based on sound exposure and perhaps fatigue, early in the morning testing looks a little better when I've done it but since it's evening that I usually enjoy music, let's go with this result:

It took around 6 minutes to test both ears between 125Hz to 8kHz. The software can plot the final results with age norms to make sure your hearing is as expected. I had some mild ear infections as a child in my right ear so I'm not surprised by the slight left ear high-frequency superiority. Otherwise, I've avoided attending too many loud concerts. Low-frequency acuity is excellent and the high-frequency is consistent with what one would expect for a guy in the 50's.

There's another hearing test available in the app called the "Digits In Noise" test which assesses the intelligibility of spoken numbers when obscured by background noise. As you can imagine, this is useful to primarily assess speech recognition. I wonder as audiophiles whether this might also be beneficial to ensure that we're able to pick up details in the important mid-range frequencies. I would imagine that "Golden Ears" should be able to excel at this test also.

Here's my curve (tested binaurally) compared to normative data:


The graph's roll-off is well in the green "correct intelligibility" zone rather than in the red "impaired" zone so I'll take that as a having a good ability to discern the voice from background noise. 🙂

I hope serious audiophiles and especially audio reviewers take the time to think about their hearing ability before making claims about this noise anomaly, that distortion, or the other "jitter" issue they ostensibly hear in audio systems. Whether one wins debates on-line with a quick wit or use the most eloquent of arguments, it's meaningless, maybe even a bit pitiful at the end of the day if we do not even understand our own limits. For guys like Elliot Goldman and Jay Caceres who seem to believe they're able to discern unlikely audible differences from all kinds of things (like fancy wires, cable risers, maybe even the ethernet switch!), I certainly hope they can prove to themselves that they're doing well in these basic self-test measurements of hearing. Their results better reflect phenomenal acuity considering what they're claiming!

Nice that they have a music recommendation portion at the end. That can be meaningful for those watching.

And there you have it. An interesting video "debate" showing off various characters and viewpoints we'll run into in the audiophile world. Obviously, I'd be siding with Dennis Burger when it comes to the majority of his comments and in taking on those questions. I think his responses made the most sense as he appreciated human biases, the use of techniques whether it be blinded listening, or measurements to find the answers (also as "sanity checks"), and using science-based understanding to rationally explain phenomena or argue against mystical properties.

I'm looking forward to that blind ethernet switch listening test with Jay's "$375-thousand dollar speaker" 🤣. Clearly, he's too fixated on the money - I do not believe this reflects the spirit of the music-loving rational audiophile. Besides, who cares if a system "measures" $1M if one cannot even be sure that one's hearing isn't objectively crap?

[An extreme subjectivist can complain all they want about guys who measure with dBs, Watts, Volts, Hz, Ω, milliseconds, etc. But they have to realize that the '$' is the worst unit of measurement of sound quality.]

--------------------

Obviously, the big movie out this week is Wicked: For Good (2025, DR8 stereo, DR12 multichannel/Atmos soundtrack). My favorite track from the musical, the sweet "For Good"; a 'good' one for karaoke night maybe... 😏

[While I typically prefer multichannel albums, not the least of which because of less dynamic range compression, unfortunately, here's an example that's inconsistent and many tracks like the first one "Every Day More Wicked" just doesn't sound great. Center vocals are fine through most of the album, but the mix has a disappointingly unfocused, and unbalanced soundstage. IMO, whoever did the mix should go back to the studio and try again.]

The 5-disc Elvis Presley compilation Sunset Boulevard (2025, DR11 average - nice!) features his recordings and rehearsals at the RCA Sunset Boulevard studio which now is the site of the L.A. Film School. Here's "Burning Love (Take 2)", circa 1972:

Hope you're enjoying the music, audiophiles! Happy Thankgiving to our American friends.


Addendum: November 23, 2025

In the discussions below, I was reminded that I have an old audiometry "screen" device here that a grumpy, neuropsychologist at the University gave me a few years back when he retired. I suspect he used it back in the 1980-90's for some research:

It's a Maico MA25 (here's the latest version) audiometer with its power supply and it can be used fully portably with a 9V battery. I see that it has ISO 389 and ANSI S3.6 certification. The left knob selects output level ranging from 0 to 80dBHL at 5dB intervals. The right knob is the frequency knob with standard 250Hz to 8kHz. Buttons are for power, left/right selection, whether the stimulus is a pulsatile tone, and the "Stimulus" button to send the tone. Pretty simple in operation.

Those are some of the most uncomfortable headphones with the rubber ear pads I've ever put on my head ☹️. I guess for sanitary reasons they're easy to clean between subjects. Poor noise isolation so definitely need to be in a quiet room when testing.

One "classic" audiometric headphone BTW is the Beyerdynamic DT-48A which was based on the first dynamic studio headphone released in 1937. I see there are Inner Fidelity measurements of the Beyer DT-48E headphone from 2011.

I played with this for a little bit and I would say the modern Hearing Test app's results using my Bluetooth headphones correlate quite well!

  1. Hej Arch,
    My first reaction to your seven points is how similar they represent the accepted practices of a cult member. Cults are often ascribed to religious groups but the mind set of these and many audiophiles share similar attitudes so common to cult leaders and their followers. One only has to browse the audio forums to understand just how fanatical and defensive some of these members become when confronted with topics such as cables, switches etc.
    I believe that because music can cause powerful emotional responses then perhaps the equipment used to reproduce the music is also regarded not only as technical tools, but an object intrinsically connected to these emotions. Amplifiers are not just amplifying a signal but responsible for eliciting these emotional responses. Reviewers will invariably describe hi-fi products with evocative and artistic language and only rarely make mention of any objective analysis. The sound will be described as warm, room-filling, crisp and fast or even slow!
    I wonder how a welder would react when reading an audiophile publication reviewing a new welding machine. For fun I asked Chat GPT:
    “The welding machine stands like a small, steadfast sun captured in a metal shell—quiet until summoned, then alive with a fierce and brilliant purpose. When awakened, it breathes electricity, weaving molten light into the world with the precision of an artisan and the intensity of a star. Its cables coil like patient serpents, carrying shimmering currents that leap forward in a shower of sparks, stitching steel with glowing seams of amber fire.
    In its presence, raw metal softens, reshaped by the machine’s incandescent touch, as though persuaded by a whisper of lightning. Each burst of radiance is a heartbeat of creation, a brief constellation blossoming at the tip of the torch. And when the blaze subsides, what remains is strength—two once-separate pieces now joined in a bond forged not by hand alone, but by the luminous spirit of the machine itself.” 😊
    Perhaps it is this strong emotional connection that clouds the senses and prevents rational objective analysis of any hi-fi product including all the associated snake oil.
    Cheers
    Mike

    1. Hey there Mike,
      That subjective review of the welding machine was brilliant man! I love it. So poetic and makes me want to go out and partake in owning a piece of "sun captured in a metal shell" - oh so manly and powerful! 😂

      Indeed, those 7 points are representative of "cultic thinking". Among the believers, there is suppression of critical analysis, strong dependence on a leader, a form of group ideology, information control (closing off of comments on websites or some forums banning discussion of blind listening tests or measurements).

      Thankfully, I think the audiophile world these days is much better than it was a decade back at least for those of us open to free discussions on forums, so I think we're making progress in that more information is available. I've seen YouTube videos where would-be-cultist leaders will tell their sheep to not go to forums or read about dissenting viewpoints.

      Audiophiles should be very careful whenever people tell you to not read this or freely think about that, and they have all the answers (brands and products!) you need.

    2. Hi, yes i was also surprised by the poetic fluency in ChatGPT’s emotional description of a welding machine. I too felt like finding something to weld. I have a machine at home that has been unused for a long time. However, we do see how marketing today focuses on emotions rather than any practical descriptions of the product. Perfume ads have been doing this forever. Car manufacturers rarely mention horsepower, torque or reliability. They want you to imagine the car as an extension of your personality or at least your imagined one! As goes for watches and more.
      Here is a nice summary with examples https://fomo.com/blog/emotional-marketing
      I must regularly, every two years, complete a medical exam where my hearing is also tested. This is a requirement to be allowed to work offshore. I still work in the industry although I am 66 and really should retire. Common demands are that your hearing should not exceed 25dB at 500, 1000 and 2000 Hz or 35dB at 3000, 4000 and 6000Hz. These values can vary depending on your specific job or work area. I did my last test a year ago and only at 8000Hz do I need an increase to 40dB. So pretty much normal hearing. However, when you had the DAC challenge a while back which my daughter aged 22 assisted me with, I was made painfully aware that she could distinguish differences between the tracks on each Dac far more easily and readily than poor old me!
      I have been enjoying Memories of Home with John Scolfield and Dave Holland released on 25th October. https://open.qobuz.com/album/nzq2wxknhrnpc Relaxed but certainly worthy of dedicated listening. Beautifully captured. Of course, you must like jazz guitar and bass!

    3. Interesting Mike,
      Yeah, nothing like the younger folks reminding us of what we might be missing! That's how I feel when I try a listening like that with my kids.

      On the plus side, I had my wife do the listening test last night and I think I preferred my ears just a little more. 😉

      Will have a listen to Memories at Home! Thanks for the suggestion.

  2. I did the hearing test using AKG K702s and I am pretty much deaf. I scored as a person in their seventies would, and I am nowhere close to my seventies. So I will bow out of anything to do with subjective hearing opinions and bitterly mourn the fact that I will never hear high-fidelity sound, along with all the money I have wasted. such is the pleasures of life.

    1. Are you sure you did the test correctly? Using the app with wired headphones seems to be quite tricky, what with all the calibration options and whatnot.

      Even if your results are as you say, I wouldn't get too despondent. Just EQ your music based on your hearing test results to compensate for them, and there's no reason why you can't enjoy music and hi-fi gear as much as anyone else :)

      But first thing you should do is get a thorough and professional (and accurate!) hearing test done rather than just relying on the app. Think of it as a second opinion of sorts.

      My point is - don't give up just yet :)

      Delete
    2. Also! For a quick and relatively easy (although a bit rudimentary) DIY solution of sorts for any hearing problems, just go the Apple route with an iPhone and Airpods.

      On your iPhone, do the on-device listening test:
      https://support.apple.com/en-us/120991

      And then switch on Media Assist (see bottom of the page):
      https://support.apple.com/en-us/120992

      Bingo presto, job done! This will get you more than halfway there I reckon :)

    3. Hey there Dan, I agree with MB,
      Did you do this on an Apple or Android?

      Make sure the test was done accurately with the proper AKG coefficients and the volume control was taken over by the app, and the app was able to calibrate everything to the proper analog output level (which I presume is dependent on your phone/tablet). I suspect it's probably more reliable on wireless headphones since the output level should be standard among the same models.

      BTW this brings up an important item we've talked about here and there which is the ubiquity of headphones and how loud we're listening these days especially when music is severely dynamically compressed to be LOUD ALL THE TIME.

      There was that recent Economist article talking about loud dynamic range compression at least temporary straining hearing in animal models. There's also worrisome surveys like this one on 18-24 year olds having "risky prolonged and high volume listening". 😕

      As audiophiles, it's certainly important to protect our hearing so we can have a long career in subjectively teasing out jitter, cable noise, and differentiating Class D from Class A amps! 😉

    4. Hi, thanks for your replies. I'm not massively upset. I have a black, cynical sense of humour, and my previous comment wasn't meant to be depressive.

      I use an Android Samsung tablet with the hearing test. I'm going to book a hearing test, but the British NHS is only for people on death’s door; everyone else has to wait months, sometimes years, for appointments, so it won't be any time soon.

      I am still enjoying listening to music. I've been playing with the equaliser, and I've turned up 5 kHz to 10 kHz. I can hear an audible difference, so I'm not completely deaf, assuming the EQ can be trusted.

      Delete
    5. Nice Dan,
      Yikes, NHS eh? Well, I think that's pretty common sentiment across the world unless one is willing to pay the big bucks privately. 😟

      Anyhow, take care of the hearing, especially with the metal music!

    6. Hey Dan, forget the NHS, just go to your nearest Specsavers, they do thorough hearing tests for free, no strings attached. See here:

      https://www.specsavers.co.uk/hearing/hearing-test

      Lol, I listen to a lot of UK radio, I heard the Specsavers ad about this several times, that's how I know about it :-)

    7. Hi, I did the hearing test incorrectly. I thought the app automatically selected the headphones from its pre-calibrated settings. While I found it odd that it recognised my wired headphones model automatically, it has only just occurred to me that it needs manual calibration, in other words I'm a wazzock

      I asked someone in their thirties to calibrate the app, and I have an average hearing range, so I’m well chuffed.

      Sounds like you're back in the crazy audiophile game! 😆

  3. Hey Arch, thanks for the great post. Thanks especially for highlighting the brilliant Hearing Test app. Was exactly what I needed! I recently went to a clinic to get my hearing tested (out of curiosity, not necessity), but had to abandon the test half way through because too much noise was leaking in to the testing room. This excellent (free!) app got the job done, and I'm well pleased.

    I have the recommended Soundcore Life Q30 headphones as it happens (I rarely use them, but they are decent for the price I got them for - 50 Eur). I turned off ANC and set the EQ to default, and did a few runs of the test to make sure the results were consistent enough for my satisfaction. I even switched between the SBC and AAC Bluetooth codec just to be sure.

    As for my test results, there is more variance right/left with my ears than yours, but overall my results are not too different from yours - up to 4 KHz. At 6 KHz on the vertical axis I get (R/L) 10/25 dB HL, and at 8 KHz I get (R/L) 0/50 dB HL. Quite a variance! But it's not a surprise to me, I've always known I couldn't hear high frequencies all that well with my left ear, it's coz of a prank in primary school where some kids popped a cap gun next to my ear.

    However I am pleasantly surprised my right ear hears high frequencies as well as it does - a fair bit above average. Not bad at my age - 46. Having one golden ear isn't a bad consolation prize if you have one dodgy ear :D

    I'm sure you must have seen that the app lets you test your hearing at even higher frequencies - up to 18 KHz. However, above 12 KHz I suspect it's not reliable since the test signal needs to be played at higher and higher volumes the higher you go, and the distortions that produces would give unreliable results.

    Anyway, thanks again for recommending the app!

    1. Hey MB,
      Yup, I tried up to 12kHz as well but I agree that it's not reliable up there. Beyond some technical issues as per solderdude below, I wonder about the lossy codec and how that's affecting the strength of the playback.

      Wow, that's a great R ear you got! Perhaps there's something to be said about how the body is able to compensate. Damn kids and that unfortunate prank man!

  4. I would like to comment on the usage of pure test tones using headphones at frequencies over 4kHz.
    Have a look at the picture linked below:
    https://diyaudioheaven.wordpress.com/wp-content/uploads/2025/11/fr-815.png
    Then have a look at the 8kHz area with this headphone.
    Chances are (also considering product variance) that an 8kHz tone might be anywhere from +10dB to -15dB. Then I have not even touched the fact that somewhere between 7 and 10kHz there is also a dip in the hearing (ear canal resonance).
    This is true not only for 8kHz but above 6kHz the response on headphones on ones head is not to be trusted.
    Ears are fine to enjoy music with but are notoriously bad as measurement device with pure tones above several kHz.
    When tetsing the hearing and using headphones I would recommend to use a known good headphone (say HD 600 or HD650) and also to not use pure tones but narrow band noise. This way the results will be much closer to 'the truth'.

    The 8kHz tone can be a hit or miss.

    Best to have the hearing checked at some ear doctor as they have calibrated gear (to the specific test headphone they use).

    1. True solderdude,
      At best, apps like this would be a decent "screen" but one should go to the local audiometrist to get the professional test results. Speaking of professional test gear, this reminds me that I have an old Maico MA25 probably from the 1980's - they have new versions these days. Anyhow, an old neuropsychologist who did auditory research at the university gave it to me when he retired... I'll show a picture of it above.

      You're right solderdude, we have all kinds of idiosyncratic pinna "shadow" from 2-8kHz and then there's the ear canal resonance somewhere around 3-5kHz. I think IEM's also will have that canal resonance higher up around 8kHz. Also what makes it hard to measure headphones and I suspect explains all kinds of individual preferences.

  5. Hi, archimago

    I would like to comment on the ""musicians generally and recording engineers are some of the worst hi-fi listeners that I have ever met" part, as I was a professional musician for a long time, holding a degree in Jazz and having also done the official conservatory exams for theory/ear training for classical music, and these days I also do some work as an hi-fi reviewer.

    I would say that in general musicians have little interest in hi-fi and are more than happy to hear music trough studio monitors - although there are exceptions, Stereophile published some very interesting articles called "Musicians as Audiophiles", and they can be read online. Jerome Sabbagh, a great jazz sax player and co-owner of a label called Analog Tone Factory, was at the Munich High End show of 2022, courtesy of Stenheim.

    I'm constantly surprised at how easy it is for people to assume their own ignorance, sometimes even with pride. Saying ""musicians generally and recording engineers are some of the worst hi-fi listeners that I have ever met" reveals a level of ignorance that it's rare and none should be proud of it - least of all saying in public, remiding me of people who are proud of not reading books. No one, I repeat, no one on this earth knows better than musicians what instruments should sound like - any pro musician has spent thousands of hours working on their instruments' sound alone plus a few thousand dollars on instruments and gear.

    We're always debating "golden ears", which is the easiest thing in the world for people om the hi-fi industry to claim, because there's no way of disproving it. Yet, I've wondered many times, how many people in the industry can easily distinguish and electric bass from an acoustic bass on a recording? A piano from a Rhodes? A violin from a cello? A tenor sax from an alto sax, or even better, a sax from a trumpet? How many can identify each part of a drum set correctly? If you barely have ever heard any instrument played two feet from you, how can you claim it sounds right? Compared to what? If you can't sell your product to the ones who know it should sound, well...

    Anyway, just a small rant, hope you don't mind!

    1. Hey there Miguel,
      A well-spoken rant is totally welcome! 😉

      Yup, I've met a few professional concert musicians over the years and have been to their homes. While they might not use "high-end audiophile" gear for playback, when I listen to music with these folks, as you noted, they actually know what they're listening to. They'll make comments about the instruments used, can identify the notes that make up the melody then strum it with their guitar, they'll pick up on subtle chord changes, comment on alternate accompaniment or singers will talk about vocal techniques and interesting lyrics, maybe critique how they would play the music differently, etc.

      That ability to analyze music is IMO the true analysis of "art", not whatever the heck this dealer Elliot thinks he's doing in a client's room with hardware he sells and switching in/out expensive audiophile cables. 🤔 For him to say what he said is ridiculous.

  6. Hi Arch,
    Using my IEMs with response very close to the Harman curve, I used https://hearingtestonline (quite similar to the Android app you suggest) and found mild hearing loss, as expected at my age. However, the 8k result was rather better than expected: 10dB better than 4k, the opposite of what I'd expect from the curve. But then is the curve meant to compensate for headphone effects? Without better specs and calibration, I can't say.
    Just writing this to confirm that anyone concerned about their hearing should get a professional test.
    Keep up the valuable content,
    Phil

    1. Thanks for the note Phil,
      A quick look at Hearingtest.online seems to suggest a pretty simplistic calibration system. I suspect the app's ability to use calibrations for different headphones in its database would be significantly better.

      Since you're using an IEM, it's possible that the typical 8kHz canal resonance is enhancing the perception of the tone on the test. Do you have some circumaural headphones to try out for the test? You likely would see a more "normal" 8kHz response with a dip compared to 4kHz.

  7. Hi Arch, I'm new around here, but reading and appreciating your blow for years...Of today's topic but still on the audio field: have you ever heard or had experience with Ian Canada and his products? He's a diy Raspberry Pi modules and full solutions designer. You can find everything on his website. I bought just one of his products, which is made in collaboration/ for Audiophonics which is a SPDIF reclocker and the results are obvious. So what I'm suggesting, if you have interest maybe to look into his products, which in my humble opinion, is really good solution at a reasonable price for what it offers. I have zero affiliation, but I got great results with the reclocker, but it needs a good power supply. One guy that built a few of his projects is Gabster, with a YouTube channel. Thanks and all the best in your work.

    1. Thanks for the note Marius,
      I see your YouTube video here.

      I don't know about IanCanada and had a look at the site. Interesting collection of geeky boards 🙂.

      Wondering if you're able to measure changes with the clocks/crystals? Feel free to fire off any findings you're able to plot out, would love to put up an article if this objectively makes a difference in your system!

  8. Hi Arch, that is not my YouTube video.That's one of the guys who brought Ian's boards to another level by implementing his solutions with the best power supply, made of ultra capacitors, by Ian Canada. Same concept of power supply, with huge capacities, is promoted by Angela-Gilbert Young on Youtube. With my post I was trying to bring to this community's attention the importance of a DDC/ Recklocking, backed up by a great power supply. And with Ian's products, which is are niche, I consider them another alternative for high end but at reasonable priced. One more thing, look on Ian's website, under Projects, for fully assembled solutions. Have a great weekend.
