This is a great amplifier! Plenty of power to listen to music or movies. It is built very well, has a massive tordial-transformer and capacitors! It is beefy. I paid just south of $250.00. I feel I did very well for the quality of amplification this piece provides!

So why my four-star rating? Simple-there is no 12-volt trigger on the amplifier! Adcom has chosen to put a proprietary trigger called AD-Link to run with Adcom products. This simply put, pisses me off! I would love to be able to leave the amplifier in standby mode when not in use. As it is, I must press a button to power it on and off after use. Not a huge deal, but inconvenient to say the least!

Sound Amazing ..a bargain at $350;no fatiguing if listen for hours if you're used to .... looking at things closer to the $350/if you Looking for "warm" nice hi-end sounding .monster .huge transformer similar design to w3

$100 BUCKS,looks good ,sounds good.Did I mention I gave $100 for it? LOL

At $100, I dont think it has any weaknesses

I got this amp about 2 months ago.A local audio/HT dealer was having a sale to move some of their floor model stuff.I know them pretty good,and their know I am always a sucker for a good deal.I was cking out all the asle items and the saleman mentioned this old Adcom amp they got in as a trade in.Being an older amp with lower power rears,they really had no use for it since they do a lot of complete HT installs.Told me a $100 would take it home,just to get it out of their way!Needless to say ,I quickly got out the check book.I am using it as the center and surround amp for my Rotel RSX 1055.My rear speakers are AR TSW 510's,and really came to life with good ,clean 100W's.$100 BUCKS!! cant be beat at that price,as it is in excellent consition.

This is a pretty neat amp for what I paid. I'm using it with my PC right now, and I am amazed at the amount dynamic power this thing has. It is sick. I'm using it with a modified 15" Velodyne sub that blew the built in amp, and this thing has breathed new life into the cabinet. Good bang for the buck if you can find one on ebay.

Great sound, looks and build quality

Tricky placement

The first thing I noticed about this player was the size of the toroidial transformer. Also I was impressed by its solid feel and clean looks. After hooking it up I was amazed by its sound quality and power. It drives 4 ohm Infinity reference speakers with pretty good ease. The amp seems to be somewhat warm and full in the lower freq. It outperformed a h/k 510 surround reciever I borrowed quite noticebly. The damping factor is impressive as well. Being quite a substantial piece of equipment placement is critical. The large toroid transformer seems to pick up hum from cables, plugs, etc. I have to keep my tape deck away from it or it picks up interference. The clean power you get from this amp makes up for any issues with placement. Highly recommended if you can find one used on the net.

Clean, clean, clean power. Dual voltage.

Weight. Heat output can get pretty serious after a few movies at higher db levels.

Great price and clean, clean, clean power. No hum when running 220v/50Hz power. Slightest of hums (I have to actually place my ear on the speaker cover of my Klipsch Tangent T-5000''s) when running 100v/60Hz. Seems to be a wonderful match for my 5.1 system (Klipsch) with a separate powered sub (Yamaha).

Detailed Highs and Lows and anything in between. Powerfull high current amp circuitry. Value for the money.

slight hiss.

The Adcom GFA-6000 is a clean and detailed sounding amp compared to my HKs TXH AVR80. Upon connecting the GFA-6000 using Monster M series cables, there is a slight improvement in detail and soundstage. Power is definetly there. I find my self listening to my old CD collections over again.

A little bright on the top side.

Got this one used a couple of months ago. Its a
very good value for the power. I would suggest
using warm speakers maybe with silk dome tweeter
instead of alluminum(if your into music). For HT
it will rock.

This is a great amp for home theater and other multichannel listening sources. I have yet to force it into clipping, even when using very old AR-2ax speakers (power hogs!). I also experienced the hum from the speakers as noted above, but didn't find it intrusive. Don't put a flourescent light anywhere near this amp though! A great, clean piece.

very dynamic, very deep bass, clean highs

none at the price I paid.

I got this amp for $370 at my dealer used. I have it connected to a Sony DA50ES receiver and paradigm 7s, cc350 and atoms in the rear. This amp was a great improvement over the amps in the Sony receiver which I thought were pretty good. It stays just warm under normal use and I cannot make the amp clip at any reasonable volume level. A well built product at any price, but at $370 its a steal.
