Another theory I've heard claiming that FETs were better than bipolar
transistors is that FETs do not have the tendency to "thermal runaway"
that bipolar transistors do, and thus no circuitry to compensate for
it is necessary, and thus there is one less thing to introduce nonlinearities.

I hadn't heard bad comments about the Hafler preamp before - which one
is it (Hafler 100 or 110) that "everyone has replaced"?
