June 25th has arrived!
As planned, this is the close-off date of the Linear vs. Minimum Phase Digital Filters Test. I hope everyone who wanted to participate got a change to have a good listen and submit their results! Thank you to everyone who did this. As usual, I'm very appreciative of the time and effort to download, load up the files, and of course the careful listening!
So, I will take the next little while to process the numbers and see what I come up with. I can share with you though that in total, I received 45 responses. This is actually close to what I imagined (about 50) based on past experience. The procedure isn't as simple as something like the 24-bit or MP3 tests done in previous years so I certainly did not expect the same kind of response.
Looks like North Americans "win" in terms of number of entries by geography :-). 62% (28) of the respondents were from North America, followed by 29% Europeans, then Asians and Australians the same (4.4% each).
Okay... I will post up the data / analysis / and conclusions when I get the information processed!
Now, on a side note... What do we have here?
A 'more objective' take for Rational Audiophiles. Among other topics!

MUSINGS: Audio Cables Summary, Non-Utilitarian Functions & Scientific Falsifiability
At this point, I believe I have examined all the audio cable claims I need to for awhile (along with some related items):

MEASUREMENTS: Speaker Cables / Wires (Canare, Kimber, and the "Frankenstein" Zip Cord)
Awhile back - in October 2014 to be exact, I spoke a bit about speaker cables, posted some electrical data, and made myself a pair of 4' Canare 4S11 bi-wireable lengths with locking banana plugs to use at home. These are the black cables you see above to the right. I've been happy with them since and as I noted in that previous post, I heard no discernible difference compared to standard 12G copper zip cord nor did I feel bi-wiring made a difference so I reinserted the speaker jumpers to effectively make this a single 11G cable (no risk losing the jumpers!).
However, I presented no measurements at that time. As I mentioned last week, since I've been doing some room measurements lately (which I will talk more about in a future post), I figured it was time to put my impressions to the test and see if I can detect a difference objectively with speaker wires. Today, I present a few measurements in 2 parts - Part I is with a very "poor" zip cord (the above image, left cable), and Part II with a well known and "audiophile approved" commercial cable.

MUSINGS: On Music Streaming, now that Apple's in the game...
So, the big news this week is Apple and the streaming audio announcement; Apple Music. Of course music streaming services have been around for years: Spotify, Pandora, Rhapsody, Google Play Music, XBOX Music, Rdio, KKBOX (Asia), etc... Take your pick. Oh, let's not forget the mother of all media streaming - YouTube! Then there's also the FLAC lossless audiophile "darling", Tidal.
As usual with Apple announcements, it seem like the word "revolutionary" gets used rather liberally (along with describing objects as having "magical" properties). According to Apple, this announcement is "revolutionary", just like MQA from Meridian is "revolutionary" I guess. Lots of revolutions going on these days :-).
Supposedly this new Apple Music service will be streaming 256kbps AAC (not verified by Apple yet) and as expected from the fringe, some folks still are up in arms over the use of lossy compression with streaming services. It's as if lossy compression is morally evil and the mere mention automatically taints the product as deserving to be treated with disdain. Well, I guess I just don't see/hear it that way (the times I actually stream music off the Internet).

MEASUREMENTS: The Effect of Speaker Grilles...
"Clothed" or "Naked"... What's the difference? |
A quick measurement for this week...
I was curious the other day as I was doing some room measurements what effect speaker grill(e)s make. My Paradigm Signature S8 V3's have typical fabric and plastic grilles up front. Simple question - How much difference does the grill make to the sound of the speaker?
