Uber expensive repair at United Radio

Anybody’s experience with United Radio (East Syracuse) as a service center? I will never do business again with these guys. They charged me $1,971 to repair my Classé Audio C-M600 monoblock amp...Forteen hours @$120/hour to replace two 16 pins chipsets...They provided me a discount on their regular hourly rate, which is normally set at $140/hour...
