Hello everyone,
my Musical Fidelity V-DACII stutters on coaxial S/PDIF input. I have been using this DAC for a year and a half, more specifically the USB-A input without problems. When I tried the coaxial input with a CD player (so, 16/44,1), I got stuttering sound and the sync LED blinking irregularly, obviously losing sync. Strangely, the higher the amplitude (loud parts of a music track), the more it was losing sync and interrupting. I tried a different source (Naim streamer, again with Red Book material) and a different cable, but got the same results. Optical input works flawlessly and, no, there were no coaxial and optical devices connected at the same time and competing for the receiver's attention.
I also checked th USB/SPDIF switch and is appears to be OK. What could be the problem here? Thank you in advance for all advice and help.

It sounds to me like you have either a ground loop problem or a missing-ground fault. I'd say definitely one or the other. Could be as simple as a bad ground connection on the MF's rca jack.
Hello and thanks for your response. Both contacts on S/PDIF RCA are OK, well soldered and conducting. I don't see where a ground loop could derive from. All units in the chain (CD player and DAC) use floating ground.
Sounds like the receiver is having issues sync'ing/locking to the S/PDIF stream.
Have you tried another receiver with the same source?
