Second, they are scalable, so if you do not need 60 watts, you can simply remove output tubes to obtain the appropriate power output for your room and speakers. Fourth, they are relatively inexpensive by OTL standards. And fifth, if you get the kits, they are easy and fun to build, with great factory support. The above are all interesting facts about why this product might be worthy of consideration. But the facts provide just a door, which, when opened, allows one to enter into a very special musical experience.
Most amps make cymbals sound like some variation of white noise.
Some even make cymbals sound like real metal, but screw up the decay after the cymbal is struck. Another good test is horns - trumpets, sax, etc. Many amplifiers get the metallic sound of these very harmonically rich instruments fairly accurately, but they also can easily make them sound too hard and coarse which makes listening to them for any length of time annoying. Again, not the M60. The M60s get the midrange right, they have very acceptable bass which is much better than most tube amps and almost as good as the Classes and Krells in this area.
