Info on PSE Studio V monoblocks

I have had my set for a couple of years now and I have the spec sheets for each amp signed by Dean but I do not really have any other information on them. Anybody out there have any experience with them?
I have a studio v for my center channel and 3 studio iv for the other speakers. I love them the only problem is getting them fixed since they are not made any more. I have a studio v that I need repaired right now,
