Yeah, I used to own that exact combo. I thought they were great. They struck me as fairly straightforward, though, not overblown in the bass at all -- perhaps the speakers were overblown? Or maybe the speakers were fine, and the source was overblown? I have to admit to liking the power amp more than the pre, but only by a small margin. I currently own harder-to-drive speakers (Dynaudio Special 25), and got a A308CR to drive them.
I have to admit, I mostly used the combo on Spendor S3/5's (extremely limited LF) (with a Sunfire Jr. sub between the pre and the power), but I did try them on other -- full-range -- speakers. My overall impression of them was that, although not perfect, they came as close to driving most speakers effortlessly, so as to make them sound like what they were, whatever that was. With just a touch of warmth. Easily the most listenable solid-state amp I've ever heard.
