− | == Reports ==
| |
− | * 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!
