I was able to buy a Sanders Magtech amp for a good price and the improvement over the SS amp I was using is pretty profound. Playing both big band and small group jazz, at fairly high volume (84 to 96 dB per my meter), and there is absolutely no strain. It feels like there would be no listening fatigue at these levels. It is a very effortless sound. Percussion, drums & cymbals are amazing, probably due to the amp's ability to power the transients so much better. I actually felt chills on very familiar tracks which hasn't happened in a long time. Playing a live Billy Taylor recording, the piano sounds more distinct, there is no congestion so that every key his right and left hand hit ring true. I think the Magtech is able to cleanly reproduce the musical peaks at the moment the piano hammer strikes the strings. The other amp clipped during this highly percussive sound, compressed the dynamic range, lost its detail, and sounded strained. The Magtech doesn't seem to have this problem. This could also be why the highs no longer sound overly bright. Maybe another higher powered amp like a Bryston would have given the same improvements.
