Which place did you end up going to?

I'd prefer not to say. They're a good group of guys who seem to be talented
in a number of aspects. And they've been more than willing to correct the
mistakes that I've asked them to correct (the alt whine, loose wires, etc).
The other things that I need to fix weren't mistakes per se, but are far
from ideal situations, and are situations that most certainly do degrade
sound quality. Bottom line is that I can live with it until summertime.
