I am in need of new equip. as my Yamaha 2095 is going south. I have 6 ohm Martin-Logan Aeon's main, Atlantic Tech center and rears, Velodyne HGS 10 sub. I do not run 7.1 yet but wonder if buying the 755 now and wishing I had the 770 in six months is the right thing to do. Any thoughts on my eqip. working well with Outlaw stuff or the amp issue. Help!
