RMB-1066 vs RSX-1055 vs RMB-1075 Amplifier Quality

[fireteam]

Hi,

I was looking at some Rotel gear as an upgrade to my system. I am currently using a Marantz SR-780 to power a set of B&W CDM SE speakers (7's, 1's and a C). I've read that B&W's are notoriously hard to power and that Rotel amplifiers are recommended. I've never owned any Rotel gear, so I was wondering about the differences in amplifier quality between the RMB-1066, RMB-1075, and the amp that is in the RSX-1055.

My Marantz SR-780 has pre-outs for all the channels (5.1 DD) so I see two upgrade scenarios.

1.) Replace the SR-780 with a RSX-1055.
2.) Add an amplifier (RMB-1066) or (RMB-1075).

Am I likely to notice any difference in using RMB-1066 amplifier compared to the internal one in the RSX-1055? How different in sound quality is the RMB-1066 (in 5 channel mode) compared to the RMB-1075?

Thanks for any help!

I think you'd be better off keeping your current receiver and adding an RMB 1075. Later on when you can afford it, add a new pre-pro and you'll have a smokin system. My experience with the CDM line only really begins with the NT series, but I know I certainly recommend separates to our clients with that level of speaker. We mostly use the RMB 1066 for custom use(multizone systems) as opposed to hi-fi use. If you want a new receiver I'd say realistically you should be looking at the 1065 instead of the 1055. The 1065 would do a nice job but the 1075 and pre-pro would do and even nicer one
