Another experience I encountered during test session with 1541 Gold DAC. I have previously mentioned that "9. The COAX input seems to be dependent on source. It sounds better when the coax input is connected with Pioneer N-50 than BDP-160. Seems to be noise are induced by Pioneer BDP-160 and there is no galvanic isolation within the DAC. When I am connecting Pioneer N-50, the sound is very clean, no noise."
Now you probably know Pioneer N-50 can share digital signal through it's digital output when it gets any signal through digital input (COAX/Spdif). Have not tried yet the USB input. So when I am connecting the BDP-160 to N-50 through COAX and taking the digital output of N-50 to 1541 Gold DAC then there is no noise I can hear or feel, otherwise which I witnessed when directly connected the BDP-160 to 1541 Gold DAC. So Pioneer N-50 not only have galvanic isolation, it is also working as Galvanic Filtration system between BDP-160 and 1541 Gold DAC.
