Is the Adcom GTP-750 any good?

For $550, you're getting a terrific buy. I have spent a lot of time listening to both the 750 and 760, and both represent good value for the money. Since the 750 sold new for just under $2k, you could buy this unit for about 25% of the original price, use it a while, and sell it for about $750 if you don't like it. With an arrangement like that, I don't see how you could go wrong. By the way, The Perfect Vision had a review of the 760 by Tony Cordesman last spring -- it may have been the April or May issue. The 760 is essentially the same unit as the 750, but with 5.1 channel DVD / SACD inputs added. Cordesman gave the 760 a pretty fair write-up.

Both the GTP-750 and the GTP-760 (and other adcom stuff)have been selling on Ubid for $220-$400 for a while now.
cheers

GTP-750 for $220 - $400? I don't think so, unless there is something wrong with it. Most are selling over $700. New, the GTP-750's were about $1300 w/o any discounting. A good GTP-750 for $550 is a bargain.

I own one and its a very decent preamp for the money and you'll be hard pressed find better in its price class. I could live with mine but I prefer the sound of my tube preamp (but it's much more expensive). I'm not selling my GTP-750 though.... Its a keeper!

Trusted source + GTP 750 + $550 = purchase IMHO. Good sound, excellent value. You may even keep it after upgrading, as Abecollins!

Cheers!
