Hi Again,

I'll take some time to explain my position (at least so you understand where
we disagree).

QUOTE: it certainly does matter a whole hoot what the CD palyer is. When
playing cds on it.

I AGREE: absolutely some CD players are much better than others

QUOTE: A 24 bit cd played will pick out layers that a 16 bit player merely
glosses over.

I DISAGREE: the 24 bit player is processing the same information  - there
are no additional layers


QUOTE: Play a complictaed piece on a 24 bit cd player and the same on a 16
bit player and there is a great deal of difference

I AGREE: But I believe the difference is not because there is more
information in this case. I believe that the difference is due to better
smoothing and interpolation. For example on a 16 bit CD recording consider
consecutive samples that differ in only the last bit. On a 16bit player
there is no opportunity to describe how the signal should change from one
sample to the next. On a 24bit player this 1 bit difference represents 256
steps in the 24bit world. It is possible to use algorithms to intoerpolate
between the 2 values (ie not leaving it to chance).

In this case with well designed interpolation you should get a signal that
is likely to match the original sound more closely. BUT this is achieved by
'making up' the intervening signal and does not relate to what was actually
in the original signal.

So 24 bit CD players _can_ produce a better sound than 16 bit players, but
they don't do it by taking more detail from the CD.

By the way the DAC in the Squeezebox 2 is a 24 bit DAC so it corresponds to
the 24 CD player case above.


I hope that was clear enough (so you understand my argument even if we
continue to disagree).

Cheers


Malcolm
