I've been the minimalist route for amp design, and the problem is that
it doesn't stay that way. You always end up thinking "if I just do
this, it will work SO much better" and by the time you are done, you
have put in all the buffered current mirrors etc that really make it
work. And in the end, why not? The bits cost bugger all.

The cost is not really a factor. The idea was to design and build the
SS equivalent of Andre's simple SET amplifier, so that those
interested could build both for listening comparison.

I understand that, and it could be an interesting experiment -
although the very different transfer characteristics of a BJT and a
triode would make it of limited value. And of course in SS it is so
much more trivial a task to do all the good stuff.

If only you could get valves that worked on positrons!
