maggies love power there are a number of good amps out there. I`m in the process of buying the 3.6 and untill the buget allow I`II be using my David Hafler Trans Nova P7000 which is 500wpc @ 4 0hms. I will eventually purchase the Audio Research D400 200wpc @ 8ohms which is the perfect am for me and my ARC LS22 preamp,ARC CD3 Player. My P7000 Hafler will always be around as my back up.
