Hello- A Slim Devices salesperson suggested I post this question, in hopes someone who knows (& has time- apparently their engineers are quite busy) can answer for all to read.
The question is: does the Slimserver, or other Slim hardware/software, have a feedback chain from the hardware (that puts out the S/PDIF) to the server (which sends the music stream to the hardware)? Normal USB-DACs don't- they run "asynchronously", with a PLL to keep the output bitrate at a speed that matches the incoming packet rate, so that the buffer never over- or under-runs. This results in timing jitter, as the PLL servos the output frequency back & forth to accommodate the not-very-precisely-timed computer packets. It would appear that the Slim system could get around this, since they have their own hardware & software. Hence there would be no real need for re-clocking equipment between the Slim device and your DAC, since the real culprit in timing jitter is that asynchronous feed & PLL follower, not the inherent jitter on the oscillator (which is usually extremely low). Can anyone tell me if the Slim system works this way? If it does, I'll be in line with my $$ right away. I am particularly interested in the equipment other than the "Transporter", since I already have an excellent DAC & really just want a jitter-free S/PDIF output for it. Thanks to any who can post the answer (especially if it's Sean Adams, who the salesperson says reads this forum & knows the answers)- Neil PS: if the answer is "yes, Slim has hardware-to-software feedback so that they need no PLL", then you should put this in your product info/advertising- for audiophiles, it is a huge deal. If I knew this to be true, I'd already have ordered one (maybe more) & be telling my friends. -- lork ------------------------------------------------------------------------ lork's Profile: http://forums.slimdevices.com/member.php?userid=17438 View this thread: http://forums.slimdevices.com/showthread.php?t=47491 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
