No sound from cdp.


I have a Marantz cd5001 I've been using with a CA Dacmagic. Recently, on occasion, I'll get no sound. I have sound from my computer, and from my tuner as well. When I click to digital 1 on my dac, I notice sometimes there's no signal coming from my cdp. Of course I also have no sound. If I take things apart, or shut it down completely, it usually comes back on. This is getting frustrating though. So I'm asking for some advice. New cdp (transport)? Or do I need to look at something else? Any and all responses are appreciated.

Sounds like the DAC is not "locking" onto the output from the transport. Maybe the Marantz is shuting off the digital output after a period of time. Turning off , then back on, resets the digital out. Could also be that the transport is outputing a signal, but the DAC isn't locking on. Have you tried a different input on the DAC from the transport? You'll need to troubleshoot a little further.
Try a different digital cable from the CDP to the DAC. If you do not have one just use an analog ic or a video coax cable.
Good points as usual, that's why I post here. I'll do a little more troubleshooting. I might just bypass the dac for a few days. I only bought it to play the files from my computer anyway.
It could be the DAC's input switch, especially suspect if it drops out while playing. Try cycling thru the DAC's inputs a few times to get it to cooperate before going the unplug route.
Sometimes just turning off the cdp and turning it back on will work. Sometimes I have to turn everything off to reset it. It never does it while playing. I'll listen to a cd and it may play fine. Take that disc out and put another in and it may not play it. The cd doesn't matter, I've experimented with that already.
