Can Monoblock be split for analog and digital


Will this work? Can I use XLR Y adapter/splitters from my monoblocks to power 2 separate devices? I have a Emm Labs DV2, and a Classe' Sigma SSP preamp. I love the digital sonics the DV2 presents. Thinking about adding analog to the mix. I don't want to use the Classe' Sigma preamp with the DV2. The preamp and DV2 will never be on at the same time. Will this result in any diminished returns? Parasitic loss?? The monoblocks in essence will be sending power to separate devices? I think? If anyone has done this please chime in...Thanks

It sounds like the switch is the way to go. Just need to find a good a quality switch. The ones on Amazon are by Douk audio, I have read some issues with them. I would rather pay a little more for a better quality switch, I could use 2, two way switches. I think? Each monoblock would then feed the preamp and the DV2 dac? Then just switch between dac for digital and preamp for analog? If anyone knows of a company that makes a higher quality switch please let me know. I appreciate the suggestions... 
That's what I'm afraid of and I think you are correct. Even with a high quality switch degrading has to occur.
