Yes, it's an interesting point, but not one upheld (in practice) by Meyer and Moran.

What I can tell you guys is that there is a huge difference between 16/44.1 and 24/192. There is too much "hash" with 16 bit, remember that every bit represents twice the information, so going from 16 to 24 you'll get 16 times more depth. Admit 192 kHz does sound softer, but at the same time it's more natural sounding, the down side , eat's up more resources.

24/96kHz maybe the best trade off ... Upsampling DACS sound horrible to me , don't likey .

This is "huge" in the sense of 'really big', or 'small but reliably detected' or 'tiny and disappears when properly tested'?

The difference between 16 and 24 bit can be detected 99.99 % of the time ...

Detected how? By whom? Or do you mean with software?

I have fooled many with extremely well recorded 16/44.1

You cannot easily tell that difference. I still believe that 24 bit has a huge advantage when you have the right equipment and that the recording is well done. Other than that, you can get many 24 bit recordings that are very badly recorded and is only a hype for selling... I bought many HD recording and they don't always reflect their format...

Many are just resampled from the 44.1 format and it does not always do justice...

Reel to reel tapes had amazing sound (when well recorded) but are really hard to get these days

With software, it's 100%.

The difference can reliably be detected by ear, but only if you really boost the volume control during the softest passages (or during the silent parts). Otherwise, it's, errrr, lost in the noise.

Absolutely true. The coloration and inaccuracy from LP are completely different.

One of the authors (meyer or moran) detected hi res 15/15 using a short section of very quiet "room tone" which was amplified about 20dB higher than their usual reference level.
