I am considering purchasing this receiver to upgrade my "out of the box" HT system. I plan to use it to run my 5.1 HT speakers plus 3 paris of ceiling speakers that run through a Jamo distribution box (currently running on an under-powered, old Pioneer receiver). I'm wondering if the zone 2 power supply will be strong enough to run 6 speakers simultaneously through the Jamo box. Specs say it has 75 watts per channel. Comments/suggestions? I am a novice.
