my ears tell me that... that's all; it's just subjective. haha, I see
subjective reports don't get you far around here.

Why is it wrong? If I drew some dots on a waveform and then connected

Intuitively, one could also say that more sample
points yield a
waveform that is closer to a continuous, analog waveform. Thus it
sounds more analog.
This is completely wrong. Sorry to be rude, but such a statement
only shows your lack of understanding. Thanks for the link. My whole point of digging
up this old thread
though, was to say that I've tried it, and my ears tell me that the
papers are incorrect.
Then please point out the errors in the paper by Lipshitz and Vanderkooy.
I'm not saying that DSD is crap. It sounds well. But it doesn't meet
the claims set for it (as shown by L&V - you need at least two bits
to have a 'linear' channel) and as a storage or transmission format
it's inefficient compared to PCM. That means that if you use PCM with
the same number of bits per second as used by DSD, you get a better
result than what DSD delivers.
well, what do you mean by better? It seems like 24 bit is already
better in terms of dynamic range at any sample rate, but if you mean
more detailed representation of a waveform (in time), it seems like
you necessarily need to have the highest possible sample rate.
Like, if I were just recording an acoustic guitar and vocals, of
course 24 bit would be the best choice.
But if I'm recording a live band, there is just so much stuff
happening at once... You can't pinpoint an exact time when the
keyboard player presses the key, and you can't pinpoint just when I
pluck that bass string. A 96 khz 24bit system might say that the two
events happened at exactly the same time, when really it was closer to
1/100000 of a second apart. Now think about how many times something
like that could happen in a live recording with many instruments and
vocals and background noise from the crowd, etc. I'd rather have the
detail than the dynamic range in that case...
