PS audio m1200

I would make sure you could demo the M1200s with a return policy. I generally have a lot of great things to say about them, but they are founded on ICEpower 1200AS modules. While they are fantastic for much low impedance performance, they are rated to a minimum 2.7 ohm load or they may thin out. Your speakers have an impedance dip under 4ohm between 100Hz-1kHz. That is one heck of a dip, and you will want to ensure proper amp pairing with it.

Also, the B&W emits a brilliant sound, such as does the Ref 6. The M1200 has some nice harmonics but is otherwise a very neutral amp. It might not be a bad idea to find an amp that has a richer tonal density to balance out the sonics with the rest of your system, otherwise it may sound too dry. 

Have you heard Bel Canto Ref 1000m? I'm just looking for cheaper amp options with high power at this point. I wish I could afford some Accuphase class A, but that's just not in the budget. My budget ran thin by the time I got to the amps. 

Ask ps audio he is very knowledgeable

you might to try an Anthem P2 amp, they have one listed here for $1,900.00 it will go down to 0 ohms (dead short) and keep on playing plus they do not get hot, room temp is all. This amp is built like a tank and has plenty of power for most any speaker you can get.

I've had one for over 10 years and you can run this thing at full blast all day everyday and it will just keep going, not a lot of reviews but the ones you find all say this amp is worth it and the sound is very neutral.
