Marantz SR5008 for $550 shipped.
Something else to consider. Unless you've explicitly wired extra circuits into your home theater room, your room's 15A circuit can only handle about 1800 watts max. You've got a 1000W sub, television, source components, lights, and who knows what else in that room. Chances are you'll never be able to pull more than 125W x 5, especially if you do end up getting a second sub.
From a different angle, your Verus Grand towers are 92dB/w/m sensitivity I think. Given a THX reference goal of 105dB peaks for full-range speakers, that's 32W. Bookshelves with their 87dB sensitivity will reach 104dB with 64W. Unless you do most of your listening at reference levels, if you're like me, you'll most often be using a watt or less.
In either case, 200Wx5 is just bragging rights.
The best reasons to run a separate pre/pro are 1) for running additional processing before amplification -- for example, a
MiniDSP nanoAVR, or maybe a tube pre-amp; 2) for driving more difficult 4-ohm speakers; or 3) abundance of money and fondness for gadgets. If none of those describes you, I think you'll be better off powering your speakers with an AVR. With that said, I would either get the
Denon X4000 now, or wait a couple of months and see what capabilities the Marantz SR5009 and 6009 will carry. If I were you, I'd wait.
XMC1s haven't had any reviews because people have been mesmerized by their audio to the point of giving up on life. I guess.
