Sukasem,

They have two completely different purposes, don't they? The Adcom is a huge 2-channel amp, and the Sherbourn is a 7-channel amp with 7 barn-burning power supplies, each running, if I'm not mistaken, at 200 watts. For the better part of a decade, the Adcom has received rave reviews; the Sherbourn's profile isn't as high. A little research on the web, however, should get you the requisite information, short of actually giving them a try.
