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.

Great! The Adcom amps are excellent and there is excellent synergy with PSB Stratus mini. Get the mark II version of either the 545 II (100w/ch) or the 555 II (200w/ch). I had the 545 II and it is very powerful. I almost bought the same speakers but I was too cheap. I had an older Adcom pre also and it was the weak link. The latest 750 pre and cdp are great.

The 545 II can be gotten used for not much doe and if you want HT get 2 more for a cheap killer HT amp set up. The 545 II have a more manageable height and will fit on more racks with ease.

Also if you research it, mods are also available. A simple effective upgrade you can do is internal chassis dampening and a detachable power cord. It is easy to do because of space inside. Great amp! I have moved up the audiophile ladder since then but I still miss my 545II, and I owned it longer than any other piece of hi-fi gear.
