Thanks for the feedback. Got similar advice at hometheaterforum:

"The RMB-1095 is a very capable amp. However, mated with a receiver for its prepro stage will of course hamper its performance. I've not heard the Rotel 1066 personally, but many who have love it. I have however listened to Rotel's previous prepro offerings(976 and 985) and didn't quite like them. I ended up with an RMB-1095 and a TagMcLaren AV32R. I've not heard the 5803 either so I can't give you any direct comparisons, but if its worth anything, I've heard the 3801, and even a cheap Parasound AVC-1800 prepro beats it quite significantly. Of course the 5803 should be a huge step up from the 3801."

"What Sihan says is very correct. In a given system, the bigger difference in sound will come from changing the processor rather than the amp, and at the moment, your receiver is holding back your amp. To give you an example, for a short period of time I had an Adcom GTP-830, itself a nice processor, mated to a Classe CAV-150 amp. The performance was nothing short of mediocre, and after I hooked up a Sunfire processor to it, the change in soundstage, dynamics, and imaging was overwhelming. To further answer your dilemma, I believe that you will get better performance from your amplifier once you have the new processor, but you will also get similar performance from a high end receiver such as the Denon."

So no final decisions have been made yet. Reading a recent thread here:

makes me unsure of the Outlaw 950. But I also know there are many satisfied owners.

When I take the Rotel amp back after work today I will be explaining again to the dealer why. During the first week I called him and explained that I wasn't hearing much difference. He offered to extend the money back period until he had a 1066 processor for me to try. That was a great offer so I said ok but I was also having trouble with the amp shutting down the Panamax everything runs through. Panamax said they were aware of the problem with high current amps, they had just devised a fix and I sent it back for the update. Then a few days later the amp started causing a audible hum through all the speakers after running about an hour. Out of frustration I simply decided to return the amp. But at the dealer tonight I'll explain the hum and see if I can take a different amp home. There is a lot of interest in the 1066 processor on this forum and others so I should probably at least hear it before taking if off the list of possibilities.
