I guess the small PSU that comes with the SBT is to the best technology. However, a better PSU with audiophile quality and price-tag or not is unlikely to affect the sound when you use and external ADC through one of the digital outputs. In my case I connect it to a Sonny 5200ES AV receiver through the coax output and I am very happy with the sound. The analog output from the Burr Brown ADC in the SBT is likely to contain noise from the power supply and I guess that it can be seen in the oscilloscope. For somebody that feels the need to improve the sound I would suggest to spend hard earned dollars in a better ADC and cables instead of the PSU ------------------------------------------------------------------------ hidef's Profile: http://forums.slimdevices.com/member.php?userid=63410 View this thread: http://forums.slimdevices.com/showthread.php?t=104317 _______________________________________________ Touch mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/touch
