Yeah, yeah, yeah..I have heard all of that crap countless times.
Look, it is simple: the cause is jitter.
The SPDIF scheme is stupid too begin with. It allows for too much
jitter. And not just any kind of jitter: jitter that is data
correlated.
As for why the SB2/3 may sound worse...the

Denny,
The timing does matter here. The same bits with different timing can
yield different audio output. Jitter does exist, although one can
argue about its significance.
If you read up on the SPDIF protocol and understand how the clock is
obtained from the data signal itself, you will see th

the thing that trips up so many technical people when thinking about
data is that if the bits are transmitted without error (or with errors
corrected), that you cannot have an audible difference. but what is so
often overlooked is that, unlike copying a computer file from a CD to a

Digital information is a stream of numbers.
I assume that when a CD is ripped to FLAC then both the CD and the FLAC
generate the same stream of numbers - that would be the FLAC-developer's

Do digital sources sound different? IMO yes, though it's dependant upon
the quality of the downstream kit to be able to show up those
differences.
Ref the SB3, it can be improved with better clocks, PSUs etc, though
don't ask me about modding, as that's far from my area of expertise.
