After good reviews and fine measurements, purchasing an SMSL SU-1 was practically a no-brainer. I'm powering it with a linear 5VDC 1A supply, using it with my decades old NAD 512 CD Player, still working well. The NAD/SMSL combination sounds OK with my Schiit Headphone Amp. BUT I found that volume control adjustment sounds scratchy. This ONLY happens when using the SMSL DAC; other sources don't exhibit this issue. So I wondered if the SMSL DAC has any DC voltage at the output jacks? Took a measurement and YES, I'm seeing 1mVDC on the right channel output and 1.5mVDC on the left channel while idling.
My question is if DC voltage at the SMSL SU-1 output jacks is normal?
Thanks in advance for any help to answer my first post here!
