Adcom Amps? How Good?
I'm looking for opinions on Adcom amps. I've noticed several e-bay auctions for their GFA-7300 5-channel amp with prices between $350-$400.
How good are they? Are they a good buy or should I wait for something like the Rotel RMB-1066?
Initially, it would be paired with a HK AVR-55 until my number comes up in the Outlaw 950 lottery 
Regards,
Kevin |

They are solid, well built amps, and compare favorably to other amps in their price range, IMO. They are worthy of consideration for those looking to move into seperates without breaking the bank.
I use a GFA-5400(125 X 2)to power my Tempest sub and it provides plenty of juice on all but the most difficult passages on DVD. I used it to power my front channels before I got my Sunfire Cinema Grand, and although it didn't have the raw power the Sunfire has, it performed admirably.

I’ve had a pair of Adcom GFA-555II amps in my system for six or seven years now, one powering the subs, one the L/R mains. Been very happy with them.

I have a GFA-5500. Excellent well-built amp. It will do 200 WPC at 8 ohms or 350 WPC at 4ohms, continuous.
That's enough power to handle most anything, especially if you have efficient speakers. No cooling fans to
make noise or break, either. It's one of the best values around in amps. It's has two channels, but
Adcom also has a GFA-5503 that is designed to be used with the GFA-5500. The GFA-5503 has three channels
that meet the same specs as the GFA-5500's two channels. Together that gives you five channels
of some serious matched power for all your speakers.
Cost for the two would be somewhere around $2,200 if you could find a good deal, maybe a bit more. |

Bought a GFA555II in 1991...using it today to power my SVS-20-39CS....works great. Almost sold it when I got my Outlaw 750....didn't have the SVS then. Sure am glad I held on to it.

I've been running a GFA-7500 for over a year now and am loving it.
150x5 is plenty for my speaks...plus I am in an apartment so I don't often (read: ever) have the chance to drive it hard.
Ahh maybe someday...
Nature abhors a vacuum. I happen to like mine.

My mains run off a pair of GFA-565 monoblocks that I have had since 1991. Rock solid, powerful, cool running and understated. I personally like the sound of the older Adcom power amps (535, 545, 555, 565, 585, 2535, etc.) and will be expanding out my amplification with some strategic purchases of Used Adcoms from Audiogon and eBay.

I'm running four Adcom 545ii (100W stereo) power amplifiers, the first of which I picked up 5+ years ago when I preferred it slightly over the equivalent Rotel of the time (while not straight-wire-with gain, it doesn't do anything glaring to the sound). In comparison, the newer 5000 series FET amps seem to trade a little bottom end for a bit of smoothness. The current home-theater amps are bipolar like the old 500 series and ought to sound similar.
Apart from alleged problems with the 5800, all the Adcom gear is well-built and affordable, and the power amplifiers compare well to others in the same price range if you're looking for something somewhat neutral.

Kevin:
Everybody has its own opinion. You got here an ADCOM group that loves their amps. Years ago I had a GFA 545, and later a 555. These were the brightest, grainiest amps I've ever owned. Mediocre bass to boot, after that, had 4 Aragons. WOW! what a difference! The one exception was the GFA-565 monos that JimN own. Now those are worth looking up even today. Superb sound from those monster monos. I missed the opportunity to buy those years ago and I'm still sorry.

My opinion. I had a GFA-535 or something. Very nice amp for the money. Then I moved on to Nakamichi, Aragon, Acurus. Never looked back. Adcom makes great amps, but there's a lot of competition out there too. B&K, Rotel, Outlaw, etc. Sometimes you get what you pay for...
If it's not worth waiting until the last minute to do, then it's not worth doing.
