This is a good price for the 5 channel version. If you only need the 3 channel version it's on sale directly from Monoprice for $350 right now...

Dude, just get the other two channels for the extra fitty. I'll give you a hundred for them! I got a 7 channel like 5 months ago because there was a crazy deal. Still sitting in the box. Got it to run with my rz-50, but sounds fine as is. This should be the motto at Slickdeals: "think of all the money you've "saved" with all that stuff you bought that's still in its original box...".

Have you tried an external amp vs the RZ-50? I still have my RZ-50 in a box to replace my 6100.

I would be interested in the sound difference between non external vs external amplification with the RZ 50 as well. My planned route is this exact 5 channel with an RZ 50. Wanted to make sure it was worth it or just use the receiver amplification.

It is pretty much the same price on the Bay direct from Monoprice, and they are showing MSRP as $500
