Bottom Line:   
The Adcom GFA 5802 was designed for Adcom by Nelson Pass leveraging the International Rectifier HexFet T03 output devices. Nelson Pass designed these amps with 3 vs the 5 gain stages used by many manufacturers which possibly leads to the smoother yet more transparent sound quality.

I use a pair of these to bi amp B&W 803s. These amps have a very deep and wide sound stage and deliver excellent inner detail in the music with absolutely no transistor glare. I've compared these amps to many others and they still out perform most on the market. I read all of the reviews on this site and frankly believe that the negative reviews are likely the result of faulty equipment, preamps or perhaps the Adcom.

My have performed flawlessly for almost 14 years. Highly recommended.

Bottom Line:   
These are great amplifiiers that produce a very deep sound stage with good detail and no transistor haze. These amps use HexFets for outputs. Nelson Pass designed this amp with only three high gain stages instead of the normal 5 stages of gain in most amps. This produces a signal path with less " handling ". The result of the design is great sound that is not fatiguing. The amp produces a lot of power and is perfect for electrostatic speakers. The only negative is heat. The amp is biased to run Class A for a good portion of its output. Keep this baby well ventilated.

Bottom Line:   
This is the only high rated amp in my price range that had this much power.I am driving a pair of power hungy SL-3 Martin Logans .It will drive the ML's with great detail,and sounstage.It is a little weak on bass,but it might be just the speakers,as some of the lower end ML's need a sub to sound great.
Ive had this amp for 3 years with no problems what so ever.

Bottom Line:   
I tried this as a last resort, as everything else failed misrably when it came to driving my Mission 770's.
It was the top-end of our budget, but we tried it anyway. To say we were blown away is an understatement. This thing is fantastic, pumping out a massive 140 wpc into 8ohms. I'm sure it will drive anything, because my Mission's were bouncing along like never before.
The sound is crisp and clean in the high frequencies, with knock-your-socks-off mids and base which is accurate, tight and well-rounded. It's almost a dream come true!
It's not very big or heavy either, which makes this little gem even more astounding. I am well impressed, and still reeling from shear delight and astonishment.
