Trying out the PS Audio Stellar Gain DAC preamp today. Wife is home so I have to have headphones on while she works. I like it. It's interesting that it shows you when the DAC is receiving PCM and at which level (44, 96, 192) but it just goes blank with DSD. I figured I'd get a little DSD logo but nothing. It definitely sounds good.
@Joe Mac have you had issues with popping noises when you switch on the USB? I get some loud pops when it switches over. I noticed the sound was up too loud on the Mac player so I switched it down to low before turning on the system and it's lessened greatly. Looked online and it seems to be a known issue. Since I bought it preowned, not a lot of recourse to send it to PS Audio to see about it. Doesn't happen on analog sources as far as I can tell. Only using my record player and an AM/FM tuner for listening to NPR.
