Using RCA & XLR connections at same time on Amp


I have been looking for a quality CD player to add to my system. Currently, I have a Pass 3x amp and a Naim av2 processor driving Joseph 22's.

The problem is that I use an Arcam Diva as both my dvd & cd player. So, I was thinking, what if I got a Mark Levinson 39. As it has the processor built in, I could leave the 5-DIN to RCA connections to AV2 for the Arcam DVD player and utilize the XLR connections from the ML to XLR connections on the Pass Amp. This way, I bypass the Naim unit entirely and use the theoretically better ML for two channel.

Is there a reason why this does not work. I was told by a Pass/Wadia dealer it would not work, why?

Also, I know Wadia and Mark Levinson have direct volume control and XLR connections, what other CD players have this processor functionality and have XLR connections?

Please advise.

If the amp does not have selector switch on the back for RCA/XLR, then it is very likely that the inputs are common (+ for RCA = + for XLR). Therefore, you do not want to connect two sources to the amp at the same time. This will essentially short the two sources together. If they are low-impedance, this could do damage. At a minimum, the sound will suck because of the loading caused by the other source.
Rkmca - what you are doing may sound okay in some cases, but it is a really bad idea.
