Rotel RMB-1085 Introduction
There are few names that are both as well known and associated with high-end as Rotel. They have a reputation for quality and power and great aesthetics. We haven't done a Rotel review around here in quite some time so we were all excited (and lined up) when they expressed an interest in having their new Class D RMB-1085 amp reviewed. Somehow, through a combination of luck, bribery, and begging, I got the review sample, shipped overnight no less.

Just upgraded to a RMB1085 from a audiolab 8000p running with audiolab 8000q pre amplifier.Fast, detailed and smooth ,neutral sounding with ample power for a large room with multi speaker setup. It may not look it but this is an audiophile grade amp.
Don't know about the ice though as the amp runs warm like any other conventional amp would.
Nice review. Any chance of getting some power and distortion measurements on the Rotel amp. As you point out in your article, linearity and low distortion have been a chanlange for calss D amps in the past.
these new Rotels have lower-model ice modules as compared to the ice modules on my 1077 (which I'm using for 2 channel listening, til i get a center channel) which is why these new ones are cheaper.
