0. Never sad better, just different. 1. I think we all agree there is no difference at all in bits, networlk connection, flac conversion and USB connection to dac always (or near always, just a far, far, far, little opportunity in USB) produce an exact 'logical' copy. SB+ has no USB but direct I2S to the dac, so... 2. If not 'data', should be time, is'nt it? But wait, Is the 'time ' of the cpu related to the clock of the signal at the dac? If not in very poor systems, no. It's not, or at east not directly. So, it's not even there... But some system are better than other in this terms, so here we have differences here too, but - as archimago pointed out - are little and seems not to be related at the cpu load or others. Other than this, you could move the data in asynchronous way and 'recklock' it just before the dac. In that sense, up to the buffer just before the dac itself we don't have jitter at all. Then if we have some Jitter injected to the dac, is because some 'rumor' reach the clock and influence it's precision. But in exactly the same way this rumor could affect the digital, it could affect the analog too, is just few cm ahead. If you measure the otput of the dac (analog) you could not understend what come from Jitter and what from 'rumor' and you could even not understand the 'real' path the rumor follow to reach the RCA couple, just like was with the old plain analog in the golden years... Those are just a speculation, I really have not Idea were differences origin, but measuring Jitter and measurinng THD or others at the analog out is different. ____________________________________________________________ SB+, Klimo Merlino + Kent Gold, Monitor Audio Studio 20 Gold SE+, Klimo reference and DIS Interconnect. ------------------------------------------------------------------------ marcoc1712's Profile: http://forums.slimdevices.com/member.php?userid=34842 View this thread: http://forums.slimdevices.com/showthread.php?t=104227 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
