I have owned Adcom amps and preamps since the late 1980's, and have found them to offer good quality for the money. The audiophile community often gives unsufficient respect to the "value" manufacturers, such as Adcom, Rotel, etc. Adcom does not spend a lot of money on the exterior, choosing instead to provide good parts quality (good toroid transformers, MIL-SPEC parts and circuit boards, etc.). I have recently been using an Adcom GTP-760 that belongs to my wife, and to be honest I am really impressed with it's sound quality. The GFP-750 preamp -- the successor to the excellent GFP-565 -- is a superb unit regardless of cost. The GFA-5802 is also an excellent power amp, though a bit large for some installations. When it comes to audio gear, my best advice is: Trust your ears. Audition the product, and if you like it, and the price meets your budget, buy what sounds best to you. I think if you approach Adcom, B&K, and Rotel equipment, you will find that it provides 85-90% of the performance of much more expensive stuff.
Adcom?
I'm concerned about some of the talk I hear on this page and other pages about Adcom products. I know they are inexpensive but are they bad? I know when people talk about louddpeakers the name Bose always gets laughed at, and for good reason. I would never own a Bose product. However, it seems that Adcom is the "Bose" of electronics. I guess what I'm curious about is the fact that Adcom almost always gets rave reviews from the press. Such quotes as "you would have to spend 3 times the price to get this kind of sound elswhere" are common. So, the question is, Are Adcom amps and pre/pros decent products for use in a high end home theater system? or are they completely useless.
