Hi,
Can someone comment on this amp?

http://www.pha.inecnet.cz/macura/follower_e.html

Seems very simple and elegant. Can I expect good hi-fi sound
out
of this? How will it compare, says, to a Hafler DH200?

It's reasonably simple, but certainly not elegant. It's extremely
inefficient. It has no gain, so you'll probably have to find a
substantial preamplifier just to drive it. It has poor power supply
rejection. It has no feedback (because it has no gain) and this is
listed as an advantage; why, I don't know. It contains a 3.3v zener
diode, which is about as poor as a zener gets.

Since I know nothing about the Hafler DH200, I can't comment reliably
on how it would compare. It's been my experience, however, that
Hafler is a superb designer. I can't imagine him designing anything
as crummy as that Macura design.
