OK, insatiable curiosity overcame fear - so I tried it :-). First, there is no audible difference between paused and un-paused SB playback of a silent .wav file, either via the SB analogue outs or through my external DAC (Lite DAC AH). There was a clearly audible difference between the DAC and the SB analogue outs. The level was about the same, but the static from the DAC sounded white, while the analogue outs had some mid-high frequency hum in there. However, that was with basic monster interconnects attached to the SB analogue, and nicer Blue Jeans cables on the DAC. So naturally I tried swapping the interconnects. That interchanged the noise as far as I could tell, implying that it had nothing to do with the SB or the DAC. It must have been the cheaper cables picking a little EM noise from somewhere. However the level for both was so low as to be completely negligible when listening to anything (other than silence). Note that the DAC-AH has an LED. This also implies, IMHO, that expensive interconnects or cables (and it's precisely RCA interconnects which are the type of audio cable most sensitive to noise) are a waste of money. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=23227 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
