Here's another fairly happy Rotel customer. I use a RSX 1055 receiver as a pre/pro, to drive Aragon 8008BB and 8002 amps to Paradigm Studio 60v3s, and CC570 center speaker. Use the amp section of the Rotel to drive ADP470 surrounds.
The Aragons are said not to match well with speakers with metal tweeters, such as the Paradigms. I can confirm this, using another preamp, or "direct", the sound was indeed overly harsh. With the Rotel in the chain, the sound of the front speakers smoothed out nicely.
There are some features missing from the 1055, that IMHO should have been there for the price asked. Things such as addressable channels (for bi-amping), separate bass management settings for each speaker, and a more precise time delay control, to name a few. Maybe the newer models do better? Thanks to the info on Club Rotel, I was able to DIY the lastest firmware upgrade for the 1055. I have read that some Rotel units have suffered from quality control issues, mine seems to have a nasty "DC offset" problem on some of the preouts, but I have worked around it.
Never the less, I like the sound quality and ergonomics of the Rotel, so it will be a keeper for a while.
