I'm building a 15' x 30' HT and need to know if I should buy the 200 watt Outlaw 770 or will the 100 watt 7100 work for me? I will be pairing up my amp with the Outlaw 950 pre/pro and will be using Energy Connoisseur Series speakers.

C-9 L & R
C-C3 Center
C-R3 Surrounds x 4
Outlaw LFM-1 Subwoofer

I don't know which wattage is necessary for this size room and these speakers. I need advice, and have appreciated the advice given in this forum in the past.
I look forward to your responses.

Thanks,
