Best multi-channel 5/7 power amp for Home Theater

I'll second the Sunfire Signature power amp. It drives my center and rears for movies extremely well today, with tons of power to spare. Years ago, when I used it for my front speakers, the 2 different sound output options made bi-wiring my speakers a no-brainer and the sound was amazing for my investment. I've got all Synergistic wiring as well - you're in for a treat, especially if you add the Sunfire. I've had mine probably 4-5 years now and never had a problem - never gets hot(or even warm!!) and always dependable.

Yes, I have the 405x5 into 8 ohms. More power in reserve is always better, especially in light of how you prefer to listen. This amp won't strain no matter how hard you drive it - it will also work with other speakers you may decide to get further down the line(power doubles into 4 ohms, for example).

I am using the Reference sub ICs for my sub - pretty impressive after a relatively short break-in period.
