i was in Sevenoaks in manchester today and they have a sale on some of their stuff. they have a display parasound 2205 5 channel power amp going for £1799, is this a good price and how big a difference will it make to M&K speakers (150s and ss150 for rears?) with a denon avc a1se driving them? i was VERY tempted but thought i should do some research before blowing soo much on an amp i have never heard before! also, anyone know of a rack that will take it, it HUGE!!!
