What amplifiers compare in quality, or are better in quality with xlr inputs, to the Denon POA-A1HDCI? I would like to start saving my money toward a good quality amplifier. How does the ATI-AT3005 stack up in sound quality? Also should I hang onto my Nikko alpha 220 amplifiers for say the rear surrounds and concentrate on a good solid amplifier for the front, center, and left speakers with bi-amping.
What price range are we talking about here?
The Classe 300WPC x 5Ch amp costs $9,000 and is not as stellar as the POA in terms of FR, THD, Crosstalk, & SNR.
The ATI AT3005 measures closer to the Classe 300WPC amp in terms of power output, FR, THD, Crosstalk, & SNR, but you can get the AT3005 for $2K (condition 10/10 - like new w/ a full 7 yr ATI factory warranty).
The AT3005 is also the same amp (internally) as the Lexicon 300WPC, which is like $6,000 or $7,000.
ATI make amps for Lexicon, Earthquake Sound, JBL, Outlaw Audio, and probably some other companies.
The good news is that the AT3005 "only" weighs like 95lbs.
Shoot, I can handle 95lbs anyday as opposed to POA's 130lbs.
The AT3005 also has 2 huge metal handles in the front, which helps A LOT when installing into your rack!
I think the AT3005, along with the Lexicon amps, etc., sounds GREAT.
It delivers over 300WPC into 8ohms and 600WPC into 4ohms, and all the measurements are stellar (although not as stellar as the POA).
But can you HUMANLY tell the difference between the ATI/Lexicon amps vs. the POA when all levels are matched using the same great speakers & components in the same environment?
That will open up a whole can of worms!
