I would think the same (your point 1). Except that vinyl is not really (as) low-rez (as PCM). Doesn't it rather depend on contingent capabilities and properties of the vinyl rig what it can reproduce out of the analog source?
TIA for the Kaoru & Shogu paper. It could offer more fodder for thought on the significance of IM distortion in this respect (your point 2).
These won't qualify as adequate referencing but here we go:
- I stumbled upon a German tonmeister thesis work that I didn't read yet (bet your German is faster - ) but which seems relevant at least in parts. I got interested b/c of the two supervisors (Maillard and Meyer) who are pretty much the creme de la creme of the current-generation tonmeisters around.
- Griesinger's "Perception of mid frequency and high frequency intermodulation distortion in loudspeakers, and its relationship to high-definition audio" is a PPt presentation (at AES 2003 meeting) and I'll email it to you. Found ref to it in a NHK Labs paper by Nishiguchi at
Similarly only skimmed through a few pages so far. He is high credibility in the audio world as I understand it.
- The Boyk piece (mosty spectral analyses) I mentioned, "There's Life Above 20 Kilohertz! A Survey of Musical Instrument Spectra to 102.4 KHz," is at http://www.cco.caltech.edu/~boyk/spectra/spectra.htm.
Oohashi et al. are mentioned rather in passing in the (too) short discussion on significance. I couldn't find anything else by him, so I just wonder.
- And an item from HiFi News with some more references at the end (though none of these are very recent
No idea who this author is.
- Stereophile had a big editorial and discussion on this stuff at the early days of SACD & DVD-A, in 2000 or 2001 I recall (try searching "Atkinson Boyk").
- Best of all, I just realized that we may be rehashing a old debate from these very pages: see http://www.audioasylum.com/audio/general/messages/129397.html...
So it seems it's by no means a new discussion, even if nothing has really been established in the meantime. Indeed, why hasn't anyone done further studies on this?
