[QUOTE="Ampdog, post: 4206, member: 144"] This is an opinion arrived at from circuit viewing, not test results, on an earlier question from Gert. Rather belatedly I looked at the circuits. Somehow I found little on the Aleph. What is its claim-to-superiority? I acknowledge the advantage of MOSFETs, but so far my own experience was of a wide variety of beta, gm, or whatever it is called in FETs. Without the ability to match, they are a no-no to me. (I did notice the designer pointing this out.) Having said that, I find a lot in the Greg Ball amplifier to recommend it, including simplicity and that he exports this with matched FETs. Some of the thinking in the Krell e.g. sometimes feeding from emitter followers also co-incides with my thinking/analysis. In the end, the harmonic spectrum analysis and stability would have determined my choice. [/QUOTE]
