I'm about to take my first step into separates and am seriously considering this amp. Right now it's a tossup for me between the Sherbourn and an Acurus A200x5. I can pick up the Acurus for $800 (used) and a dealer demo Sherbourn will run me about $400 more. Is it worth the price difference? I've read nothing but good reviews on both of these 5 channel amps, but I'm leaning towards the Sherbourn. Anyone out there who owns one with an opinion to share that might help me make my decision? FYI, demoing these units is not possible, so I'll be making the purchase without hearing them first. I've got Polk RT800i front mains, Polk CS400i CC, Polk R10 surrounds and an Infinity powered sub. For now I'll be using my Nakamichi AV-10 receiver as a pre/pro. UPDATE: My dealer demo 5/1500A deal fell through, as in they didn't actually have it. Sooo, I'm in the market for a used 5/1500A. If anyone has a line on one, let me know?
