Adcom GFA-5802 vs Sherbourn 7/2100A

I have not heard Sherbourne. I have a 2 channel Adcom and have heard some others. I think they are a good buy. My impression of them is that they have a slight bass hump. I switched from an Audio Quest to a Transparent speaker connect and my opinion of Adcom has actually gone up. I have a GFA-5400 that drives a pair of Dynaudio Audience 62's in a second system, the Adcom drives them very well and with proper ventilation there is no heat problem. I've had the Adcom amp and preamp now for maybe 5 years without any trouble what so ever with either. And that's with having them in a work out room where they only get driven hard.
