If I were in the market for an amp, I would look at the power-> noise ratio.. try to get something with .005 or less THD, are you fimilar with transistor theory? If you are you should have no problem chosing an amp if you can look at the shcematics, I have found some manufactures that have the actual schematics online..personaly I would stay away from the 7 channel amps that are powered from a single power supply, as the only amp that I have see that I would consider would be the earthequake product, sense each channel has its own power supply. Rat, I would say get a 3 channel amp, and a 2 channel amp. Maybe bryston. Or ATI.. depending on your budget.. get a 2-300watt 3 channel, and a 150-200watt 2 channel for your QS8’s..
