My brother had some Red Wine stuff and was very disappointed in its reliability. After two service trips on a single unit, he sold it off. Turnaround took about ten weeks.
It would have been helpful if you could state more precisely what gear are you referring to?
Was it 30.0, 30.2, 70.2, Isabella, Isabellina (the only RWA products from ground up) or one of the modified t-amps or other gear that RWA just happened to worked on ?????
I own(ed) 30.0 integrated, 30.2 amp and Isabella/Isabellina pre and never had a problems. YMMV
