Dave, I just disconnected the cable from the DAC and recorded that... The noise is definitely coming from the analogue stage of the SB3. According to JA's plot he's using a 16-bit signal and has noise below 100dB - not sure how that works if 16-bit=96dB....? +-------------------------------------------------------------------+ |Filename: no DAC just cable into sound card.jpg | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=8812| +-------------------------------------------------------------------+ -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
