How do Adcom power amps sound?


Hi,

My system is : PSB Stratus Mini, Cambrdige AZUR 540a and a Toshiba 3950 ( unmodded) in a 20x20 room with the speakers placed about 6 feet apart and mostly listened to in the close range.

If you arent familiar with my speakers they are a pretty tough load, 4ohm at 86db.

My amp only puts out 40-50 watts into 8ohm and 65 into 4ohm, as you can tell its having trouble powering my speakers, so im considering buying a power amp for them.

Im on a pretty tight budget , and the Adcom power amps seem to be priced right, so im considering something like the GFA-555 ( 200 wpc 8ohm and 325ohm).

Does anyone have any experiance with this unit, or similiar Adcom units? How do they sound, would it be an upgrade, power and quality wise over my current cambridge amp?

Id probabaly use the cambrdige as a pre- amp untill i can afford something better.

FWIW for a lower priced amp I would consider NAC, they honor the music and have consistantly gotten good reviews...

Adcoms are good entry level gear. However, I agree with the comment about the McCormack. It's in a different league.

My new ( to me) Adcom 300 by 7 powers my B&W's just fine and solved a preponderance of problems. I am fairly new to high end audio, so take that into account. I have heard my same speakers on a McIntosh amp in a demo room and heard no difference. I am certain more seasoned ears would disagree, but for 1700.00 (slightly used)I do not think I am missing out on anything that would be audible (to me). What I did notice, like night and day, is that doubling the power made a slight difference in volume but a huge difference in overall sound quality.

I agree with The Kid, Brainwater, Bufus.....

The Adcom GFA555 is just too bright. By "bright" I don't mean, "detailed"... two different things. The GFA555 Mk2 is a bit easier on the ears, though it's still noticeably edgier than a midrange/tweeter amp should be. That said, the original bipolar GFA555 is a rock solid *subwoofer* amp... highly detail and dynamic... just downright impressive.

I can't comment on later Adcoms since I haven't owned any.

The Forte Model 6 is the Class A-A/B version of the Model 4 (Class A) and it sounds nearly as good as the 4. The 6 provides a healthy 200x2 as opposed to the 4's 50x2. It sounds like you need the extra 6dB provided by the Model 6.

The Forte amps are simply amazing performers, regardless of price or build date. Current price for a very nice Model 6 or Model 4 is $400-700, depending on cosmetics and your luck :^)

Good LUCK!!
