Bi-Amping PMC Fact 12
 

I would like to bi-amp PMC Fact 12 speakers (considering purchase soon).

One choice is to get 2 x Bryston 4b3 Stereo Amps (300 wpc). and use each amp per speakers with one channel driving the lower frequency and other channel driving the higher frequency.

Second choice is get 2 x Bryston 7b3 mono’s (600 wpc) and use one per speaker.

Which setup will result in best sound quality – dual mono’s or dual stereo’s?

go with the 7b's, much nicer control

I own a pair of Fact 12s. I initially had one 4b3 powering them and then upgraded to a pair of 7b3 amps. The sound has improved quite a bit... more 3D, more airy, the mids and highs are definitely sweeter, and larger sound stage.
