Ya, I get that all should be earthed, but my DAC and Preamp will not run signal transformers very well. Neither have a ton of drive, but they sure sound AWESOME. It has 2 short interconnect paths to ground. :) Could I transformer couple the AC Ground of the preamp?
Steve. What is this component exactly?
"From server to USB interface - I use a XMOS interface with galvanic isolation"
Give it up man. Don't bogard every secret! lol Also, is it bit perfect? Pass DSD, High Resolution, etc?
