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.
