Why not just get an Anthem P2 power amp, I have an Anthem MRX520 that I use for HT and watching TV, and I have the P2 hooked up to the preouts along with a sub so when I listen to just stereo 2.1 channel I just switch everything with the remote, it really is very easy to set up and my system was set up with the ARC by the place I bought my MRX520 from for $50.00
The P2 can drive any speaker down to a short so from 8ohms basically down to 1 ohm
