I finally got round to finishing the Nelson Pass designed amplifier using SONY static induction transistors or power jfets. Rarer than very rare things , the 2SJ28, 2SK82 had a good reputation for sound quality, so had to be tried. Initial thoughts are it is very good, delivering a nice detailed punchy sound, maybe because it's got a low damping factor, about nine!, coz I am using it without feedback. In comparison with my previous best amplifier which is a home brew class A bipolar, the bipolar sounds a little more "hi-fi", i.e super accurate it will interesting to hear how the pass design sounds with extra feedback, supposed to sound more "neutral", so I guess it will narrow the difference between the two amplifiers.
