I too use a consumer amp for my my speakers but a pro amp for my sub. For kicks, I ran my mains with the pro amp for a bit and was really impressed with what a 300 buck amp could do. No sonic signature what so ever and would drive the heck out of my speakers.
If I had to sum it up, I would say that the pro amp, my MPS1 and my Rotel all drove the speakers the same, I could not tell any difference in them.
If you want an inexpensive amp, go pro. The hassle is with setting up a system to turn it on and off, doing a fan mod and all the power cords if running more than 2 speakers.
If you want to go consumer, EMO is hard to beat price wise. I had unresolved issues with mine and will not buy anymore products from EMO.
If money is no object, get a Bryston. -or- if you are somewhere inbetween, like me, find a used Rotel...
Oh....and I like the toast you guys make....
