Polk Audio C400.4
I have this amplifier biamping a set of MMC6500 component speakers using the PreEQ button. The sound is phenomenal and tuning was a breeze with the PreEQ.
Polk's components are top notch and excellent performers. They look great too! Their high price is easily justified. You won't find this amp new cheaper anywhere else. Trust me, I searched.
