Reports[edit]
- On one bought used (07/2012) everything runs great, only the volume control grates a bit. Rich and clean performance, with CD Direct possibly a little little bass (subjective) but that can be compensated via bass and double bass (no longer CD Direct).
Even (m)a used amplifier acquired in the late 90s has always run smoothly and completely reliably (this is probably also a result of the fact that he never had to wait in a [damp] storeroom / cellar). For purists, an all-around great (real) analog amplifier without any A/D converters and servo drives (remote control). Otherwise, very cleanly processed and even after more than 20 years old optics as good as new!
