Funniest snake oil theories

A golden eared friend of mine doesn't like live acoustic music. He says it's too bright, and has exaggerated dynamics.
Go figure.

I suppose his personal reference is music at home with its compressed dynamcis. Funny to read this, as the credo of the golden ears in the seventies was reproducing the real dynamic of classical concerts - technical hardly available at that time.
 
I have spent many many years playing in bands and one of my reference "sounds" for judging reproduction quality is drum cymbals. I realised reading descriptions of high frequency reproduction in forums (despite the terms "livelike" and "real" being thrown around a lot) that the main reference for many people seems to be their mom's kitchen radio they grew up with...

You nailed it, the cymbals were the reference for transparent sound.
 
It's a combination of recording technique and reproduction. Ambisonics didn't catch on so we are stuck with SACD surround sound. I can't get a 5.1 or 7.1 system into my living room. Then you have the issue of reproducing the infrasonic 'breathing' of the venue.

You can get close. I heard a wilson audio demo some (mumble) years ago that got half way there in that you felt like you were looking into a church. But the total immersion was missing.
 
My references are things like singing in King's Chapel. The acoustics are to die for. Sadly both recording and reproduction in a 'realistic' way is challenging.

Yes, I can imagine, listening to choir in Lichfield Cathedral was quite an experience. Is it the sheer physical size of the reverberant field that makes it impossible to reproduce in a small space?
Watch this lecture by David Byrne on different music for different rooms. YouTube
 
...Yes, only the latter is actually level matching and only the latter is relevant to blind tests. Let us hope that people who claim to do tests with matched levels have used electrical matching, otherwise their results are quite meaningless....
Only limited to comparison of amps with a single pair of transducers. On comparison of amps with various transducers of different sensitivity, SPL matching is required.

Yes, that sort of rev field experience is near impossible to reproduce, even with headphones. But, I find it enough that a good recording evokes the acoustic memory, if you know what I mean. Oddly, I also sometimes prefer to set the lounge volume to ear bleeding levels, and listen while in another room, letting the sound "waft" around the house... (we have no near neighbours 🙂 )
 
Nice lecture Evenharmonics, I like the fact I got a mention during an important stage of the evolution of modern music 😀 Also it was interesting what he said towards the end about faking it and apparent authenticity, as an example one could take the erroneous phenomena of the modern Hipster :lickface:
 
When serious audio designers refer to 'voicing' amplifiers, we don't necessarily measure frequency response differences. Scott, you have some device that has an added frequency deviation for some reason, but it is not a normal audio amp or preamp in performance. Where would I, for example be able to change the overall frequency response of one of my amps? Where is that cap, inductor, etc that I could possibly adjust to effect the frequency response, except at the very extremes of the hi and low response where you don't care about in any case?

You can use a gyrator on a voltage divider in the signal path to create dips or peaks, depending on where you include it in the circuit. Just one thing that comes to mind.

But that would not be introducing the right kind of distortion. In the wonder box Scott described FR deviations were voltage dependent so that necessarily implies distortion of the sine wave.

Edit: use real shitty caps in your gyrator and the voltage dependent part is also taken care of
