I use Integra DHC80.3 & Onkyo 9-channel amp PA-MC5500 (4 ohms @ 300 wpc). All JTR speakers, Quintuples L,R, & C with Triple 8's for all surrounds. My normal listening volume for movies is -5. The PA-MC5500 9 channel amp is a damn good one for the price and can be had for $1400 to $2000. You really don't need tons of amperage to run JTR's even though you can but it is a waste of $$$$.
