I just got one of these amps about a month ago, and honestly, for the cheap price I paid, it really delivers more than I had ever imagined. The imaging is good, the sound is crystal clear. I can't even really explain it. It's like being there. I have a small square listening room with this amp in it, and it's not even hooked up to great speakers, but the sound of this amp is just totally unexpected. I am going to try and get some high efficiency speakers for this amp, as it's power output isn't that high unless you really crank it, and that doesn't seem like the thing to do. However, strangely, I find myself listening to it at a lower volume than with my other tube amp, and I enjoy it even more. There's just so much detail. My other amp is a recent tube amp that cost about $1000, but this thing which I got for way less just seems so much clearer. I've never had a vintage stereo amp before, but if this isn't close to top of the line, I'm sure I'll be constantly amazed at my trip up the ladder.
All that being said, the information on this model, or ever this brand of stereo amplifier is pretty sparse online, and the price i got it at seems stupid low for the quality. is this amp a sleeper? does anyone have any more information on it? I figure I'll have to buy a manual from some website that does that kind of thing (unless someone has a pdf).
All in all, I am VERY satisfied with this amp. When I bought it, it had crap pictures, so I was sure I could resell it with a nice profit, but I've fallen in love with the thing and probably won't get rid of it until I find an amp I love more, which honestly may take a while.
