B&W Matrix 805's, need amp, pre-amp, or integrated

Not a big fan of CJ and I do not know how it would match with 805s.

Bada DC-225. $1200 from Pacific Valve. 30 day money back and one year warrantee. I had the earlier version of this amp while I was waiting for my Viva and it was incredible for the money. Full remote control too - meaning input switching. I've heard the 805s many times and I believe the Bada would mate beautifully with them. IMO. No relation to the seller, of course.

fwiw - I've paired my B&W CDM1NTs with a Musical Fidelity A5 Integrated - pretty sweet synergy, imo. The A5 is smooth on top, grips the B&Ws down low and has plenty of oomph for clean dynamics w/ headroom to spare.

Musical Fidelity A300 integrated and two small subs to fill out the bottom end

The classic recommendation for 805s is big solid state power. Emotiva is a good recommendation in your price range. An Adcom GFA 555 II would be very affordable. The Wyred 4 Sound amps might fit, too.
