It's hard to find people who can work on modern electronic equipment. It's even more surprising to find people who can do this and who are nice and easy to deal with. The front counter person was friendly and courteous. When I picked up my amp, I had a question, so the tech came out and spent fifteen minutes explaining to me what I needed to know. (Turns out I had blown the amp because the speaker wires in my apartment we shorted.)
I wish I could find other businesses like this.
