One approach to this problem is adding a powered subwoofer. Not only will this relieve the Prima Luna of most of the "heavy lifting", it will also provide both bass extention and power. If you search for subwoofer threads in these forums, posts from Bob Reynolds, Shadorne, and Drew Eckhardt (among others) will likely prove mighty educational (they did for me).
BTW - The $600 Velodyne SMS-1 sub controller (X-over, Room analyzer w/calibrated mic, and PEq) allows seamless integration with many sub/main combos. The $600 SVS sub has almost unbelievable specs (I haven't heard it, but Bob Reynolds is a big fan)for the money. I use the Velodyne SMS-1 with Velodyne SPLR subs and several different main systems. The results are outstanding. For $1200, I can't think of a better way to go.
Good Luck
