If budget is an issue I found that the Parasound HCA-2205AT is a much better amp then the B&K Ref 7250. I owned the B&K for a brief period before returning it. The Parasound has subjectively more power, detail, and extension at the extremes, and doesn't blur details on transients like the B&Ks. Compared to my Bryston 7Bs which I use for my L/R the Bryston is more even across the frequency range, has even more detail in the lows, mids, and highs, and is more transparent sounding. And of course is more powerful. I've recently auditioned the Classe CAM 350s and thought they were wonderful, but expensive at 3500 each.
