I have been testing a modified Squeezebox2 using Andrew's super regulators - there is a definite improvement at the RCA outputs when a super reg is used to power the DAC chip:
http://www.seanadams.com/sb2_super_regs/ Also trying some hacks to the oscillator and s/pdif circuitry - I've been fiddling around with some jitter measurements and will have more data on that soon. Replacing the external PS with a linear supply, although it doesn't appear to have much impact on the DAC, *does* reduce jitter measuably (from about 3.5ns to 1ns pk-pk). This simple THD+N test is not expected to reveal any effects of jitter at the DAC output though. -- seanadams _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
