Thanks for your corrected response. FYI- the clocks in my DAC are +/- 10ps. I never said the SQ differences I'm hearing are jitter related, that was 325xi's call. Like many others who have posted on this forum, I'd like to see a digital out only product with AES/EBU or I2S outputs for use with an external DAC. I don't need the TP's DAC functions. A PDA style display remote would also be nice. -- jhm731 ------------------------------------------------------------------------ jhm731's Profile: http://forums.slimdevices.com/member.php?userid=7685 View this thread: http://forums.slimdevices.com/showthread.php?t=32993 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
