Sorry to challenge your premise, but why are you starting out thinking that you want to bi-amp with Rotel(s)? One of the toughest things to do in a system is overcome complexity getting everything working well together. It is very difficult to get coherent sound across the frequency range when bi-amping. When it is done, it is usually because there are few good alternatives, such as when dealing with super power-hungry speakers @ low impedance. You don't have any constraint like that.
IMHO, a good powerful tube amp like those Sufentanil suggests or others make much more sense to me. Sell the Rotels and increase your budget. For real bang-for-buck, somebody advertised a pair of Consonance monoblocks modified by RBH Sound Designz. Bob Backert is a real genius, those will beat much of what's out there! Cheers, Spencer
