«  Excellent »

Acquired to replace a newer Marantz (PM50), I felt regret. And it has absolutely not been the case. This amp is amazing, as much by the fact that it is little known by its quality. I also have a NAD3020 enjoying an excellent reputation and, frankly, it is far below. Much faster in very powerful and detailed bass. Spent at Audio Precision, the marantz displays a distortion less than 0.01% over the entire audible spectrum, measured performance and not "manufacturer" of a model 25 years old (after adjusting the bias currents)!
No regrets, this is a very good amp.
