I have the 100's and the sound when running from my Onkyo surround receiver was anemic. I bought an Anthem MCA-20 which is owned by Paradigm and love the improvement it made. This amp is 225 Wpc and has an auto on feature that senses when it receives a signal and switches on - cool. The MCA-50 is the five channel version of mine. A Stereophile report stated that the two channel RB-1080 was a bit lacking at lower volume levels and this might apply to the RMB-1095 as well - you may wish to check into it. I don't notice any lack of oomph at low volume with the Anthem. With the new amp my bass firmed up big time and the dynamics were improved immediately. Soundstaging was also improved greatly - both side to side and front to back. A good power cord on the amp will help greatly as well - check out http://www.virtualdynamics.ca/ . The rest of the folk here are right though... lots of power and lots of current and you'll be happy.
