I had a nice basement system including a Classe Tuner 1 and a Classe CA 100 amp.
When the tuner failed, I left it with the repair shop and after a month they said it needed a part that had become unavailable. I looked up the part and it had been made in Europe and out of production for a while. So I bought another Classe Tuner 1 used.
Some years later, the CA 100 amp lost a channel. After three months, my repair shop said Classe had changed ownership and no longer supported repair of pre-acquisition products. So I replaced it with a used working unit.
I eventually gave the system to a son in college. When he moved and threw it all away, I didn’t feel too bad.
Of course, I never bought another Classe product.
