Nice to see this review and measurements of the RB-1070.
Back in 2004, I had purchased a Marantz SR5400 receiver and Paradigm Studio 100 v3 towers and CC-570 center. In 2005, I was at a local stereo shop in central Ohio, and they had a Rotel RB-1090 almost 400wrms/ch sitting there for only $1000. It was their floor model, but still worked, and they even said it would still have the normal warranty, so I just couldn't turn it down. I haven't regretted it, and it still works now. Later in 2006, I bought off eBay a Rotel RMB-1075 the 120wrms/5ch for $625, which was actually a floor model from some other stereo shop, and they even threw in some The Link 100 from Transparent Audio Laboratory interconnects.
Just yesterday, I was doing some listening tests with some 5.1 DTS CDs, some various movies, and some just stereo CDs. I'm testing many speaker positions and angles even before the room is completed. I have tried many songs and movies. One that stood out was Paul Hardcastle 5 -->
In the Beginning. I was absolutely immersed in the sound. I kept having to check if I was truly in stereo mode on the receiver and had to confirm that the center and surrounds were not on. I closed my eyes, and the 100s just disappeared and literally sounded like surround sound with amazing center imaging but even more fascinating was how much sound I heard at the sides and even slightly behind me. There were a few other tracks on that disc that were quite good, but even if you don't like Paul Hardcastle, this one track is one to try. Not all my CDs sound like this, but I'm always looking for more stuff to try.
I know some have commented that the Rotel amps don't have much life or are this or that, but others have praised them as very musical and good. I can say I have been happy with mine all these years powering my Paradigms. And now I see at a local used electronics store they have a Rotel RMB-1095 200wrms/5ch for $1000. I want it so bad, but using budget for other stuff at the moment. If it's still there when I am ready, I will definitely get it.
Marantz SR-5400 is sitting on top of the amps but rotated because I'm in the process of building my new home theater and stuff is just all over. I am just doing initial room layout and listening testing and trying to decide on screen size and speaker position, etc in my 13'w x 19'd theater room.

I read this review
after buying my RB-1090, but it confirmed that I made a good purchase.
