Can Monoblock be split for analog and digital

If I understand you correctly, you're suggesting having the output of two different devices connected together to drive the same amp, with the expectation that only one would be powered on. 

Depending on the circuitry of each device (which I am not familiar with), it's unlikely this would provide the results you are hoping for. Most likely, the unpowered device would at least provide a low-impedance load which would be difficult for the powered device to drive, and it could result in damage to one or the other device. 

I think you are better off adding a passive switch at the input of your amps to switch between two inputs. 

It's really not ideal.  The apparent output impedance of a solid state device when turned off or muted is complicated.

Why don't you try using the SSP in bypass mode??

It's not the ideal situation Erik. Even in bypass it stifles the DV2, I'm trying to utilize the volume control on the DV2. As Jaytor said the unpowered device would still be a low-impedance load. The monoblocks are Classe' CA M600's. The passive switch is a good idea but it will be a PITA. I like the DV2 direct to the amps. I appreciate the input...

Jaytor, what kind of passive switch did you have in mind? You have the configuration correct. As you indicated the switch would be needed to keep the low-impedance out.

Something like this would probably work. I'm not sure how good the connectors are, but it's relatively inexpensive to give it a try.
