The Adcom 750 is a fine preamp. It's just a far cry from the best. Still, at it's cheap aftermark prices, I think it is a steal for midfiers with highender aspirations.

Viridian: ...Or not. I'm proud to say none of my my gear is recommended. I even have several issues unread. I used to read it cover to cover and now it just gets in the way of the music. Advertisers will always hold sway over the readers despite what JA would have you believe. Richard Hardesty has some good thoughts on this.
Sorry to hijack the thread. The Adcom is still viable and will do fine for many of us. The pitfalls of passive operation are largely myths, ime. Setup is everything. Happy Ash Wednesday!
They are made by Chinese Elves!
They have evil spirits lurking inside, with bad vibes constantly emanating from them.
They are constantly breaking down.
They make other audiophiles smurk when they see it in your system.
They sound like chopped horsemanure.
They look stupid.
They never work properly.
They are made by Chinese Elves with bad breath and who are flatulent.
That is why I use one.
Used Adcom stuff is SO inexpensive that if you use any of it (as I do) you should hide it...or buy fake faceplates so people think you have hipper stuff (by "people" I mean audio geeks who, to be fair, are people too). Plenty of reviewers think the amps are "un-musical" or "not quite (fill in the blank) enough". Uh...OK...BUT I use (among other stuff) an Adcom GFP715 preamp that sounds GREAT, and I've owned a bunch of their amps including a 535II and 5300 I still use. Good cables, speakers, and other nice things on both ends of the chain make it all seem to work better of course...and, having been a musician/studio and live sound engineer/audio freak since the mid 60's I've had TONS of other "high end" brands. Although some might have been worth the multiples of $ above the Adcom prices I paid, my Adcom stuff has always been less trouble, and as I said before, if you use good power conditioning, cables, etc., you might save enough to get out and see some music. Maybe I just got lucky and my Adcom gear was built by better paid or more relaxed "Chinese Elves"...but recently a friend who has identical speakers to some of mine came over and noticed my Adcom driven system sounded better than his current VERY expensive carefully set up rig...maybe his ears were waxy...you never know.
The Adcom GFP 750 was designed when most components provided a maximum of 1.0 volts on their RCA outputs. Most current (2010) components provide a maximum o 2.0 volts, and the Adcom IS NOT as graceful when handling 2.0 volt input levels. Go to PartsExpress and order a pair of 3db RCA inline attenuators and install them between CD/SACD/DVD-A/DVD sources and the GFP-750 RCA inputs.
