You're going to laugh, but I'd look at Marantz AV8802a for an AV processor, if you're interested in one. I don't know the sound of Jeff Rowland, so I'm not sure what to recommend for a center channel amp. Maybe a single Parasound JC1 monoblock? They are going for $1800-2200 on ebay.
You could always go with the larger Marantz AV7011 receiver. It has a larger power supply for better power output, but it's still not going to equal a good amp.
