I have a bad case of upgraditis, plus my h/k AVR 520 has been giving me a couple of problems, so I'm ready to go down the separates route. I'm taking this one step at a time, so I'll be using my receiver as a pre/pro 'til I can get (afford:b) a dedicated pre/pro. So I'm looking at getting one of the following amps, in no particular order: Marantz MM9000 ATI AT1505 Parasound HCA1205A Adcom GFA7400 Rotel RMB-1075 Any other amps I should be considering in this price/performance range? Any opinions, good or bad on any of my choices? I'm running Axiom speakers in a 5.1 configuration, at least for now, but that's always subject to change. BTW, I'm not too keen on buying used, at least not online, so please keep that in mind. I guess I'm looking for a good online retailer or a store here in NYC. Thanks! PS Does anybody have any info on Atlantic Technology's P-2000 pre/pro?
