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.

So your just reaching behind the amp, & switching from a Xlr connected system, to a Rca connected system. Sure this works, 2 systems all on one amp with just a flick of a switch. Bypass a preamp w/ the 39 & connect right into the amp via variable out, & enjoy!

I did almost exactly what you describe with a Bryston power amp and a Resolution Audio CD-55 player (which does have XLR outputs and an analog volume control). Works like a champ, as long as you can easily reach around to the back of the amp to switch the input.

Don't have any specs on the ML-#39, but one thing that will work for you is a two input/one output transformer volume control (passive pre). I have one that has both XLR and RCA inputs..it has balanced output to my Krell amp. I can switch between the two on the front panel of the passive unit (no need to switch amp cables).

I may (not sure yet) sell my unit in a week or so if the amp I have for sale on Audiogon does not sell.

There may also be some kind of high quality switch box you could buy, not sure about that one.

Warning: Some amps, especially those that are not truly balanced share some parts at the balanced/unbalanced ports. So, while you are using balanced, you might be sending a signal back up the line to the unbalanced components. The switch, in this case, is not designed as a 'cut-off', but more like a router.

If you happen to have both systems on at the same time, you might be in for some serious, big time trouble.

I understand McIntosh would be one case where you must avoid this.

BE CAREFUL!!!!!
