I currently have 22s,vp100,qs4s and a home built sub powered by a qsc amp and running from an onkyo 797. I just graduated college in december and have a job and hence, money! I plan on getting 80s,vp150 and 4 x qs8s and the ep600 in about 6 months. But first I want to get amps because I will be eventually going seperates and I just plain want to purchase some amps. I was torn between the bryston, parasound, and aragons and after listeing to them all decided on the parasound halos. Now heres my real questions, Should I get the A21 to power the 80s alone and the A52 to power the rest or would it be better to get the A51 to power the 80s, vp 150 and side surrounds and then the A23 to power the back pair. My room is 16 x 26, carpeted and dedicated to listening and theater. Thanks for the input, dave.
