I have MG 3.6/Bryston BP-25MC/2 Bryston 4BST/Bryston electronic crossover. I use HT ProSilway MK II and HT speaker wire. Bi-amping made a MAJOR improvement to my system in a room approx. 19+ X 28+ with a 14 ft cathedral ceiling (lg room) and there is more than enough power to drive the system to very loud CLEAN levels. I would recommend Bi-amping to anyone. Bi-amping with the 7Bs would be perhaps better but in my room somewhat over-kill, but..... If you don't use Bi-amp set up use bi-wire to MG 3.6 as that made a big improvement with only one 4B-ST. Better, I'm sure, with 7Bs.
