I'm presenting this video, with no context given, at a symposium for the arts & sciences around a campfire on next Wednesday. Beer will be served. I will report my results.
Excuse me, but the remotely activated tuner introduces an imperceptible amount of noise into the signal path which totally colors the sound. Obviously for the best warmth and tonal balance you have to use a fully-manual potentiometer knob.
I think there are two proper audiophile responses here.
One is probably something along the lines of a dual ganged rotary switch with an array of hand matched resistors for discrete, repeatable volume changes without the alleged sonic inferiority of potetiometers.
The other is probably something along th lines of "put some blobs of Fimo all around your listening room"
Once upon a time, someone discovered that you could use blu-tac as a means of getting better coupling between your speakers and stands, and then audiophile catalogs started carrying "speaker coupling putty" which was just blu-tac in a different wrapper.
Then of course there's all the shit with special green magic markers (which cost or more!) based on flawed premises about "light leakage" on CDs.
I really have no idea how anyone can fall for the "transparent audio treatment stone" bullshit, either. At least the name implies what it does - ABSOLUTELY NOTHING - but why would anyone spend hundreds/thousands of dollars on that nonsense?
I've been on the Audio Advisor mailing list for years because I bought my speakers there (they were on clearance and were relatively cheap), but their catalog is mostly full of audiophile nonsense and every time I receive it I start out reading it as if it's clever satire of audiophile bullshit but then about 1/3 of the way through I can no longer keep up the pretense and then I get sad.
