Naw, it's a plus for conservative design.
One thing that seems to be missed in this discussion about home brewing
amps was clearly pointed in a comment in this thread -- the key to solid
state amp design is THERMAL design and protection. Those are very
different skills than most amp designers of our generation learned, so
at least in part, it's an "old dog new tricks" problem, not a limitation
of the technology.
