"Come to think of it, had it been 88.2 kHz, we wouldn't be in this conundrum."that's basically what Harley said:
"
The great musical promise of a consumer format with 20-bit resolution and a high sampling rate has a bitter flip side: The millions of listeners who continue to use their existing CD players to play 44.1kHz CDs will hear degraded performance.Why? The Toshiba-led consortium wants the audio-only format to have a sampling frequency of 96kHz. If 96kHz becomes the standard for the consumer release format, professional recorders will also operate at 96kHz. Because 44.1kHz CDs will be with us for a long time, high-resolution digital master recordings must be sample-rate–converted to 44.1kHz for the conventional CD release. For at least a decade, most listeners will play 44.1kHz CDs.
The problem is that unless unrealistically complex interpolating digital filters are used, sample-rate–converting from 96kHz to 44.1kHz will degrade sound quality. This point was illustrated by Dr. James Moorer, co-founder of Sonic Solutions, who presented a paper at the Audio Engineering Society Convention in November 1996 explaining mathematically why converting 96kHz to 44.1kHz can introduce audible artifacts (footnote 1). "
My conclusion is, then: CD is a dead format (the decade in which we would still be playing CDs according to Harley is now over) and CDs now do just sound bad for the reason listed, unless they are recorded native in analog or at 88.2kHz, and carefully mastered.
Hard disk based high rez recording and downloading from the internet, etc. can all happen at high rez without ASRC. I don't see why DVD or DVD-A at 24/96 would contain these noise products, assuming recording was native at 24/96.Also, I ask again (as elsewhere here in the forum on another thread): why are you so sure the bad vibes you are hearing are from ASRC as opposed to from other distortion products (RFI, etc.)? And why would these artifacts only be audible using tubed amplification (not that you made that claim)?
