If you like your speakers, I'll guess you do. Get rid of the MC352 to free up some more cash...thats "WAY" to much amp for those speakers...100 watts a side is overkill.
If you like MAC...stay with MAC tubed gear.
Or,
Pick up a tubed integrated or tube amp and tube preamp of your choice with a lot less power.
You should have enough cash left over for a nice cd player...or transport and DAC of your choice.
You will still have enough power to blow the roof off, and a lot better sounding system to boot.
