Has a lush, smooth unfatigueing sound without diminishing clarity or low level details. Excellent factory support.

The tubes couldn't be changed without an update from AMC.

What was a fine amp became an even finer amp, when after owning it for 5 years, I had this amp updated by AMC. They installed interchangeable tube sockets (can't really understand why they didn't do this originally), put in new Sovtek tubes and updated some electronics etc. for $135.00 including return mail. And they returned it in a week. Not a bad deal. Now the good part. First of all it's absolutely dead quiet (the preamp plays a part here too). I can turn the volume to maximum, put my ear to my JM Reynaud MK 2's and not hear a whisper. I've owned 8 amps, including receivers, integrated and separates, but this is a first for me. It also has to be one of the coolest running class A tube amps around. It has 2 very quiet automatic fans under the output tubes that seldom turn on. The amp and preamp are very reliable, never had a problem. Tubes seem to last a long time since the original tubes were still running strong after 5 years, just got the mod so I'd be able to change tubes. The Sovtek's made a signiicant improvement and I guess there are probably even better tubes, but I'm extremly
happy with this amp as it is. It does all the things good tube amps are known for. Now of course all this is true of the AMC 1030 tube preamp also. Without which the amp wouldn't sound this good. By the way, the preamp was also modified. at a cost of $115. Highly recommended.

I just got the amp in today. I purchased it off of Ebay for 380 dollars, new, in the box with warranty.

I have been running it since about noon today (it is around 10pm now) and it is sounding better and better! It started out sounding a bit lousy, that has since cleared up! It is a very smooth amp, with nice width to the sound. I can pick up details from my music that I never knew were there, mostly pink floyd live albums. Some of the songs that I know like the back of my hand have small parts and bits that come out GREAT. On one song, you can actually hear the snare being rattled by the bass and other sounds during the recording. I'm very pleased. I AM however coming from a 300 dollar Onkyo reciever, which was good...until now!
