Okay Doug, that clarifies the matter a bit; you don't want to use a stereo receiver, but instead a mono amp. Sure, Zone 2 preouts can send the same(or for that matter different)program material from your 3805 to the VP150 in another room, but it's not a good idea to do it with just a Y-connection. The left channel sound, for example, doesn't know that it's supposed to follow just the branch into the amplifier, so it also runs up the other leg of the Y into the right channel pre-out.
Here's a discussion of the matter, with suggested circuitry.
