But there is error correction in digital sound technology, too, isn't there? darrenyeats;234105 Wrote: > The only areas of debate are where signals get converted into numbers > (recording, mastering, ADC) and where the numbers get converted into > signals (domestic player or transport e.g. SB3, Transporter).

But the OP's question was about the digital domain. He was asking why his DAC sounds different when it receives a stream of numbers from his CD player and from his SB3. If they sound different, then the two streams of numbers are different. Surely we can all accept that. Either the difference is in the digital or the psychological domain. darrenyeats;234105 Wrote: > Hence if FLAC and WAV sound different the cause must be something > affecting the physical player - differences in RFI from network > activity, differences in noise from on-board processing etc. - or (very > likely this is the reason) psychological factors. > Darren I think, Darren, that you might be looking for problems where they don't exist. Banks have networks, and RFI, but they don't lose bits, why should music equipment lose bits? Networking systems are robust - what goes in comes out. I'm surprised that this discussion has got this far without anyone mentioning jitter, which usually sends eveyone running for cover. If I can store software and recover it, and trust my bank statement, surely storing digital music and recovering it is a doddle. The technology is mature and there is huge and effective error correction where it is needed. 'Golden eared' hi-fi enthusiasts often tend to report differences they 'hear' as simple fact, like saying 'I looked out of the window and it was raining', without taking into account their subjectivity, what side of bed they got out of that day, etc, etc and without expressing any hesitancy or doubt about their opinions, or recognizing that they are trying to detect very tiny phenomena. I suspect that many reported differences are psycohological rather than actual. Surely many of us can agree on that. -- DennyL ------------------------------------------------------------------------ DennyL's Profile: http://forums.slimdevices.com/member.php?userid=8446 View this thread: http://forums.slimdevices.com/showthread.php?t=39113 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
