You have to be careful when looking for 5 channel amps. Since the manufacturer assumes that you'll be using this primarily for HT use, they tend to make them sound "exciting". As such, the bottom end may be slightly hyped for impact, the mids are slightly forward for increased vocal clarity and the top end slightly "hot" for added "detail". The response is quite a bit of a "rollercoaster" ride. As such, they sound great for movies and such but typically do not do the best with music. A long term "ride" with some of these amps, much like a rollercoaster, will tend to make you "sick" and "fatigue'd".
One 5 channel amp that others have suggested sounded pretty good was made by the same folks as Golden Tube Audio. Can't remember the name, but i have seen them for sale here and in other places. I'm sure that someone will help me out with what company this is. Only problem with these is that the company is out of business. Since some dealers still have these brand new and as demo's, they are closing them out relatively inexpensively and may even be covering the warranty themselves.
Other than that, you might want to look at some of the B & K's if you can find them used. Not the last word in detail or refinement, but typically a good value and on the smooth side of neutral. This should help to balance out your system also. I would avoid any Acurus multi-channel amps even though they can be found at excellent prices on the used market. They simply would not be a good match with your speakers as you have described them. Hope this helps. Sean
