Nice setup, very neat and clean! I would think you'd want an amp with generous current delivery for those B&Ws. I really liked the Butler tube/MOSFET hybrid amp that I had for a couple of years. It was powering some Gallo Ref. 3.1s and sounded great. The Butler TDB-2250 would probably be a good amp for you...
