My worst equipment failure experiences have been with Classe gear.
Both a Classe basic amp the CA-100 and a Classe tuner the Tuner-1 failed at differeint times. These were designed before the B&W acquisition of Classe, and the post-acquisition company would not provide service support -- no service locations, no replacement parts, no circuit schematics.
My impression was that not only did Classe products have dubious reliability, but also the company did not care about customers and could not be relied upon beyond the initial sale.
Of course, I vowed never to buy another Classe product.
