i recently got a bryston 7b mono amplifier for free from a friend, i hooked it up to my yamaha amp and ran my 2 front speakers and it sounds 100 times better then just using the yamaha reciever, is this amplifier basically just good for 2 speakers or is there some way i can use it with my surround, i tried watching a dvd but it just drowns out all the other speakers, any help would be great thank you
