On Magic Beans "True Target": Dirac Live 2-Pass Procedure.
![]() |
| Sunset on summer 2026... |
Ahhh, fall is coming and can be felt in the air here in Vancouver. At this time of the year, I get the compulsion to make sure I finish discussing topics I had examined in the summer and wrap up loose ends.
A couple of weeks back I discussed the Magic Beans Audio "True Target" app, an interesting program that I think can help improve sound quality for many audiophiles who use DSP in their rooms as a technique for "speaker correction" - that is, a system that flattens the direct sound coming from one's speakers above the modal and transition frequencies while respecting sensitive zones in the speaker response.
I mentioned near the end of the article about a "DLBC (2-pass calibration)" procedure. For completeness, I figure I'd give this a try and discuss in this post.

Magic Beans Audio: True Target. DSP correction fine tuning, concepts, and effects.
In my previous post, I discussed target curves and gave examples of curves you might want to consider when implementing DSP correction in your sound room.
While the use of full-range target curves is not uncommon, as discussed, there are those who advocate against doing so and would insist that only partial corrections in the bass frequencies up to the Modal+Transition Zones should be applied. There are of course some good reasons for this line of thinking which will be addressed.
As you can see in the comments last time, I had a long discussion with Joe Mariano (aka Joe N Tell) of Magic Beans Audio about his product called True Target. I continued my discussions with Joe via E-mail and he provided access for me to the Pro version which allows export of the curves to Room EQ Wizard in order to have a deeper look under the hood at how the system works.
The picture above was taken right before one of my measurement sessions with Magic Beans highlighting some "tools of the trade" used to perform the tuning.
Let's talk about the Magic Beans* True Target app.
[Standard version regularly priced at US$249 should suffice for the vast majority of users, Pro version US$399 allows up to 128 channels and unlimited daily calibrations.]

Room Target Curves - then, now, and options to try...
Be it resolved that there is no such thing as achieving sonic perfection - technically at least based on objective ideals, but "perfect" can also be a subjective state of mind.
In domestic homes, we're simply not going to be able to achieve near-perfect rooms. Likewise, no sound system will be absolutely transparent although the digital electronics side will get much closer to "perfect" than analogue playback and loudspeakers. Furthermore, beyond what we can say about our domestic playback systems, despite all the care and detail-orientedness put into a recording studio, they're not identical even if they followed published standards (like ITU-R BS.1116, or EBU Tech 3276), and besides, is there ever such a thing as a perfectly engineered recording? Or a perfect performance from our favorite artists for that matter?
While perfection might be out of reach, let's not turn away from the pursuit of what is reasonably accurate which is something we can all do to some extent whether it's choosing better-engineered gear, working on small room acoustics, or using DSP to improve frequency response and/or time-domain performance at our listening position. Regarding the specifics of DSP room correction, let me refer you to previous articles covering various methods here, here, here, here, and here.
The intent of this post is to focus on the topic of Room Target Curves which we define and apply when doing EQ and DSP correction. Let's explore a little history, what they are, what they look like and considerations for what to try at home.

SUMMER MUSINGS: True audiophile aspirations; recent events in the audiophile culture - end of Atkinson's Stereophile measurements, YouTube influencer legal drama.
Through my years as an audiophile, I've come across articles in magazines and online talking about hobbyist "aspirations". At audio shows, and seemingly each new issue of magazine we read, we're introduced to the latest and greatest piece or gear, the next "must have" item to consider in this never-ending path of upgrade to satisfy luxury consumeristic appetites.
Given that it's "Summer Musings" season, let's take some time to think about what I think is the most important aspirational item in all of the audiophile hobby - your room. And since in the last month there have been other events happening in audio news, let's also talk about the fact that John Atkinson has retired from doing measurements for Stereophile magazine, and the interesting legal drama around the case of an "influencer" (Michael Gefteas/The Greek Audio Geek) and social media.

SUMMER MUSINGS: "Final" ceiling absorption 😉. AI-assisted summary of Floyd Toole's thoughts on early reflections treatment & discussion on this.
Hey guys and gals, it's July and thus time to enjoy some summer jams, BBQ, and family time ahead. And of course getting into the "Summer Musings" season here on the blog!
Let's "shoot the breeze" and talk about a couple of things in this post related to discussions over the last while with room treatments and acoustics you might want to consider for your own space.
First, as you can see in the picture above, despite the self-proclaimed statement that I was "done", I just had one more little addition to add. I cleaned up and optimized my seating area a little and realized that the rear ceiling panel wasn't exactly overhead. So I added an extra 2' x 4' x 0.8" PET panel immediately overhead above the main listening position. [I also spent some time optimizing the height channels and DSP recalibration along the way.]

Ceiling Absorption Panels (AudioSilk branded PET material 2'x4'x0.8", doubled thickness).
With the recent discussions about room acoustics and treatments, I thought it would be good to continue on this theme and move forward with the next logical step for my listening space. Let's talk about ceiling sound absorption as you can see installed in the picture above.
For years, I've been thinking of doing this but really didn't want to put something up there that could damage the walls. I definitely would prefer not to drill holes unless absolutely needed. Recently, I had some positive experiences with 3M's Command Strips when I put up some picture frames and artwork around the home. These double-sided tape strips were designed to be removable without damaging painted walls. Looking around at options, it seemed that this could be a reasonable ceiling installation solution within weight limits.
On Amazon, there are various options for acoustic absorbers these days. I settled on a package of 4 sheets of 0.4" thick x 2' x 4' AudioSilk-branded polyethylene terephthalate (PET, non-toxic, non-irritant, made typically from recycled plastics like bottles) absorber panels at a good price (~US$110) along with some strong 2-sided tape for doubling up the panels for thickness and of course the 3M Command Strips to stick it up on the ceiling.

On Envy, "Cope", and just plain Reality in Audiophilia. More GR-Research/Danny Richie drama.
After writing the articles looking at room acoustics over the last month, I thought this would be a good time to discuss another observation about the psychology and culture of the audiophile hobby and some of the claims that people make.
As I noted last time, room treatments like the IKEA Mittzon absorption panels are far from the exciting products highlighted in magazines each month or even popular forum topics commonly discussed. While they do review realistic, non-controversial room treatments once awhile (like this), I would find it shocking if one day I opened an issue of The Absolute Sound and saw an article reviewing the Mittzon panel!

Sound Absorption: IKEA Mittzon Floor Standing Panel (+ GIK Acoustic panel).
Greetings audiophiles. Finally, I'm back home in Vancouver after my Asia trip. I love traveling but there always comes a time to look forward to "Home, sweet home." And music to listen to in my personal sound room of course!😌
In this post, let's talk about perhaps one of the most boring things you could buy - a sound absorption panel. Made all the more pedestrian because this one comes from IKEA. At a retail price of US$230 each for the smaller (but IMO adequate for my home audio) 27.5" x 61.75" x 3.125" panel, the IKEA MITTZON Floor Standing Acoustic Screen is inexpensive and easy to find. There is also the larger 35 3/8" x 61.75" model if you prefer for just a little more - US$250.
While this may look boring, I must admit that as I've experienced more and dare say, "matured" in this hobby, the most interesting upgrades do not have to be high-tech active gadgets, bear fancy brand names, or the stuff that seems to capture the latest hype.
No friends, always remember the most important components that contribute to sound quality! Digital technology in particular has reached levels of performance where diminishing returns are quite easily reached these days. Make sure to explore other "domains" and products in your search for high fidelity audio.

Audiophile Malls Asia: Highsun/Haiyin Plaza - Guangzhou, China. (And thoughts about China and the global order.)
Last time, we talked about Seoul's Yongsan ETLand, so moving along in my Asia trip, let's check out another audiophile mall, this time in Southern China, in the city of Guangzhou. I've been in this city before (as per 2016 post) but not at this exact location, the Highsun/Haiyin (name used interchangeably) Plaza.
It looks like in the last 10 years, this place has really become quite concentrated with many audiophile stores.

Audiophile Malls Asia: Yongsan ETLand - Seoul, S. Korea
I don't know about you guys, but I'm like one of those husbands/boyfriends/partners who sit outside surfing the web at women's clothing stores. So while "the girls" were out shopping and getting pedicures in Seoul, I decided to take a couple hours' detour to the Yongsan ETLand which is about a 10 minute walk away from the massive Yongsan subway station (take Exit 3).
I suspect in the Western world (North America and Europe), it's quite rare to find a good concentration of stores selling hi-fi hardware any more, if even this was ever the case. Unless one is fortunate enough to have a large dealer in town, audio shows seem to be the only place left to see a large number of brands under one roof. However, as you might remember for past articles (like this, this), in Asia, the concept of an "audiophile mall", or "hifi-mall" still exists, so let's document some of these places in 2026... this time, we take a peek in Seoul.

MUSINGS: On high-end audio component prices, inflation, April Fools and peak "greedflation"?
[Some of these thoughts will trickle into the psychology of other luxury products beyond audio. Also, we'll be talking about dollars and cents in this post. Since most audiophile goods are priced in US dollars, let's use that through this post, with early April 2026 currency conversion as needed.]

Crosstalk Cancellation/Ambiophonics: Updated CTXMatrix Lite with standalone processor & 60° speaker angle support.
![]() |
| Significant changes in the UI from the previous CTXMatrixBeta release. |
I want to remind 2-channel "immersive sound" lovers about the potential for using stereo crosstalk cancellation (XTC) / ambiophonics playback to enhance the 3D soundstage. You might have already heard of uBACCH in the audio magazines and on forums - why not try a similar effect for free (or through a small coffee donation)?!

Do HDMI cables make a difference for IIS/I2S/I²S-HDMI audiophile DACs?
It's taking a bit longer for my testing of the inexpensive I²S/IIS/I2S-HDMI DDC boxes due to some unexpected results which I'm chasing down currently; hopefully that gets resolved or understood soon.
In the meantime, let me address something that folks might be curious about related to this topic of the I2S-HDMI interface... Does the HDMI cable make a difference to the sound quality?
As with much of audiophilia wherein some members of the culture have the belief that "everything makes a difference", obviously this is not the case and I do not recommend this kind of mindset. There are many things that don't make much, if any difference (as discussed here and here) based on experience and understanding principles of the technology.
Since I have not seen measurements examining the effect of HDMI cables on I²S performance from a DAC, let's do some testing here.

Visit to a "more subjective" leaning friend. And something like Synergistic Research "Transducers" (HFT, GCT, ECT...) to try.

Hey everyone. I'm still waiting to finish the measurements and write-up of the USB DDC boxes discussed last time (a few things I need to double check on!). In the meantime, I thought I'd share some thoughts and pictures with you of a visit I made to a friend, Paul's, place. You'll see that he is much more of a "subjectivist" than I am.
Above, we see his listening room which is capable of multichannel playback as well for music and movies. He's a multichannel enthusiast who values the immersive experience and has a large library of surround content in PCM and DSD - great to see!
Clearly, Paul is a Linn fan with almost an all-Linn system. He has front Linn Akubarik Exakt (Katalyst) active speakers, an Akurate 225 center channel, and a pair of Akudoriks as rear/side channels. Over the years, he has been experimenting with Linn Space Optimisation and wrote an article about his experiences (he contacted me after he saw my tests with Linn SO last year).

| This SMSL unit also does MQA decoding for those who want the feature. Unlike the Douk, this box only has an LED to indicate MQA decoding status but does not tell us the PCM or DSD samplerate. |

More Audio Potpourri: What's the best sample rate converter? The other father of MP3 (James D. Johnston "JJ"). Are measurements important? And TAS' "objective" confusion.
For this post, let's discuss a few other audiophile items that have come my way in recent weeks.
First, let's talk about something I haven't brought up for awhile now: sample rate conversion (SRC).
A few weeks ago, Spoon (a.k.a. Steven Elkins of Illustrate) sent me an E-mail about his new src.hydrogenaudio.org page evaluating and ranking the qualities of various software sample rate converters. I believe the page has been online since late 2025. Check out the forum discussion about the project as well.

Audiophile Potpourri: December 2025 web traffic among audio sites, price of cables poll, and flashback 2014 while looking ahead.
Let's have some fun this week on miscellaneous topics.
Occasionally, I'll highlight items I've either written or found on audio discussion forums I think would be good to share. One reason I decided to start doing a blog beyond just contributing to forum discussions was precisely because while the public forums are great for interactions with community members, meaningful posts often become obscured behind pages and pages of chit chat, irrelevant responses, and sometimes unpleasant arguments.
[I've unfortunately witnessed situations where very meaningful threads are closed off prematurely based on the bias of moderators. Even worse, threads with useful discussions might be erased entirely from existence which I feel is an slap in the face of well-meaning participants who put their time and efforts into thoughtful reflections. This is nothing new in the audiophile world; for example last year Stereophile scrubbed their website of all public comments accumulated over decades!
While I acknowledge the right of a website's owner to do such things, that doesn't make it any more palatable. I certainly understand the need for moderation in removing nonsensical, trollish, unethical, or crude statements that add nothing to promote thoughtful discussions.]
Speaking of forums and websites, I thought here in early 2026 it would be fun to explore website traffic numbers of some of the most common audiophile/audio sites using a common metric. One can get monthly visit numbers from Similarweb for free, a well-known website traffic tracker.

miniDSP UMIK-2 USB Microphone: analog gain & optimizing self-noise. Plus audiophile gear pictures from "No Other Choice".

miniDSP UMIK-2 USB measurement microphone (also ambient noise floor, measurements of my system using Dirac Live with Paradigm + SVS subs)
Well, as mentioned previously, it was a great holiday season and here's another gift from Audio-Santa 🙂 - the miniDSP UMIK-2 measurement microphone. I bought this through Solen.ca here in Canada and they did a great job with the order and quick shipment. Amazon Canada often has limited stock of miniDSP products.
I'm sure the miniDSP company is well known to many audiophiles at this point. I bet many of you, like myself, already have one of their UMIK-1 microphones which I've used in a number of the acoustic measurements on this blog since 2019.
As you can imagine, the UMIK-2, initially released in late 2020, is an evolution of the UMIK-1 with upgrades which we'll talk about. First, let's have a peek at the physical device itself.

More Bass: The SVS SB-2000 Pro subwoofer (sealed, 12", 550W, DSP, Bluetooth)

Over the holidays, Santa brought me a new SVS SB-2000 Pro subwoofer (currently US$900 black ash, US$1000 piano black, Canada: black ash, piano black) for the system in the sound room. As you can see, I got the slightly more expensive shiny piano black version. As usual, I bought this from typical consumer channels.
On this blog, we've talked about full-range sound, including the importance of subwoofer(s) in order to experience "fully" all there is in our recordings. As a pop, rock, electronica, orchestral, movie-lover, the ability to experience down to 20Hz (even a little lower into "infrasound") with adequate power, and low distortion is all part of what it means to achieve "high-fidelity" audio that is transparent to the source recording. As usual, it doesn't mean I can't enjoy my music without these sub-bass frequencies! It's just nice to know that I'm not neglecting content present in those lower registers as provided by artists and audio engineers.
During the pandemic, in the spring of 2020, I bought myself an inexpensive 8" Polk PSW111 to use as an "accessory" subwoofer to help fill-in the bass response in concert with the mighty Paradigm SUB1 (1700Wrms, 6 x 8" drivers), my main subwoofer that achieves frequency response down below 20Hz. For these last 5+ years, the little Polk has done its job reasonably well but it clearly has limits. For example, when pushed up in level, I can hear the "chuffing" from the small ~4" diameter down-facing port. Also, a ported 8" sub like this can really only be expected to reproduce down to the mid-30Hz at best.
And so, moving ahead, let's spend some money to retire that little Polk sub to my main floor living room, making space for this SVS! 😁
