The source is the CXC transport connected to the DAC by Coaxial connection. I have a verified connection to the DAC.
I know, what are the odds both amps aren’t working. It doesn’t make sense.
I’ve checked and rechecked all cable connections to each component multiple times. Still I’ve no sound from either the DAC or the phono preamp, OR with the Preamp connected in the loop. Nuthin! Amps are on now with new tubes all around. Still nuthin! Pulling my hair out!
