I mean 0 and 1 are abstract representations, they don't exist as such. The digital information is basically carried by an analogue signal that codes it, so it would potentially not be immune to perturbations. How much those perturbations affect the sound is another question. Anyway, I regret I wrote that because the point of this thread was not to reopen for a n-th time the theoritical jitter question.

The reason why I was thinking of a Jisco rather than a UPCI is because it is not locked to a single frequency. While most of my music now is 44 khz, I am also getting more 48khz files (like the Linn music), and a UPCI wouldn't handle both. As far as the DAC is concerned, I am interested in the icing on the cake right now. I am satisfied with my DAC sound (at least with the CEC drive), and as it already costs 8,500 USD, there isn't much to "upgrade" with 500 USD darrenyeats;239175 Wrote: > Chinanico, > I would invite a friend round and do a little blind test. > > That's a great idea... and might put things in perspective as far as CD transport vs SB3 as digital sources. For any other kind of upgrade, though, I don't have much options to try them before buying, as I live in China right now and it's hard to get things in, even more so just to try them... The rationales behind my choices: - 1. getting rid of the switching power supply: some say it improves the sound, some say it reduces the AC pollution on the other gear - 2. Noise "killers": might be an alternative way to get rid of the pollution from the switching PSU - 3. Some prefer Toslink (and I already have decent result with one), but a better one might bring something - 4. Not sure about this one, except Coax potentially beating Toslink ? - 5. That would be to close the gap between the digital sources (as claimed by Altmann) by working on jitter... -- Chinanico ____________________________________________________________________________________ CEC TL51X / SB3 > Audiomat Maestro > Jeff Rowland Concentra 2 > System Audio SA2K ------------------------------------------------------------------------ Chinanico's Profile: http://forums.slimdevices.com/member.php?userid=12794 View this thread: http://forums.slimdevices.com/showthread.php?t=39810 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
