Hi, I have recently decided to purchase 3 A/V-2's and 2 A/V-1's for use in a 5.1 set-up. However, I need/want to purchase new components before I purchase new speakers(I feel it would be a crime to hook such fine speakers up to a sony receiver). I'm curious as to what other owners are using to power their A/V's. I would like to stay within the recommended power ratings and thats where I am having a problem with choosing a pre/pro and amp(or receiver), the A/V-2's are rated at 100 watts/ch @ 4ohms and the A/V-1's are rated at 100watts/ch @ 8ohms. I have already emailed GR research and asked for power and equipment recommendations and while I am waiting to hear back from them, I thought I would find out what other owners are using. Thanks to all who reply, this forum has been a great help in determining the upgrade path of my HT and it is much appreciated.
