Wilson Alexia 2

I'm using my MSB Reference DAC as the pre which has an extra balanced input for my phono stage.  See my full system description.

No McIntosh.

These are good amps to choose: Krell FPB700CX / FPB750MCX, Pass Labs XA200.5/.8, Mark Levinson No.33

I'm currently powering my Alexia's with Conrad Johnson LP275M mono's fitted with KT120 power tubes. Those have the power and finesse to do the big Alexia's justice. From time to time, I  rotate them with my Bryston 24B-SST mono's. The low end grip they povide is quite astonishing, but for my overall taste I prefer the big CJ's. My old Levinson No. 23.5 does an admirable job as well, but I've become addicted to monoblocks over the years. Common to allo f these is my Aethetix Callisto Eclipse preamp. I really like the suggestions of those big Krell amps. I've had several Krell pieces over the years and find them to be first rate sonics and build wise.

Sorry, I meant Bryston 28B-SST not 24B-SST. I guess I'm getting old.

@carey1110 For Alexx V i might also look at the KSA i800 Monoblocks. Thats 1.6kw/channel in 4ohm !!
