Contribution of processor in bypass mode


What contribution to the sound of a system does a processor make in bypass mode? My Oppo BDP-95 is doing the processing and sending analog to my Cary Cinema 11a, the inputs of which are set to bypass mode. Is the Cary affecting the sound or merely acting as a conduit between the sources and the amps?

I would call Cary and ask what the signal path is.

On my Cary SLP-05 2 channel preamp the Cinema Bypass just shuts a relay that bypasses everything. You can even turn off the preamp and the signal goes through. The only residual effect is whatever you get from the input and output connectors and the closed relay, which should be pretty small. My guess is the 11a does a similar thing, but Cary can tell you. When I asked them about the SLP-05 the tech looked up the schematic to check. Once you know the signal path, you can decide if you can hear a difference with it in or out.
Once again, it simply must be tested to know the effect. The effect of the Pass Through may be small or great and no company is going to tell you, "Yeah, it degrades the signal significantly..."

Dbphd, one rule is paramount; try every conceivable permutation of system development with the gear on hand. Very surprising, good things can happen when juggling gear. You may find a very pleasing combination yet! Some of the best systems I have built have been the result of inspiration to try something unconventional. Just don't do such things late at night when tired; bad things happen when half asleep and hooking up gear. :)
Douglas - I suggested that he ask Cary about the signal path, so he knows just what it happening in the unit. It is the simplest way to answer the question of just what the unit is doing internally. It could be a straight bypass with a relay, like in my SLP-05, or it could bypass part but not all the processing. A call to Cary can tell him that. I did not suggest that he ask if it will degrade the signal. I suggested he ask them about the signal path and then try it both ways and see.
Dtc, yes, I think we're agreed there is an informational component and experiential component to Dbphd's question.
