Paradigm Studio 60/100 v3 for music/HT

I wish to upgrade my current system with the focus primarily being music (rock, jazz, blues, classical) with the capability to do home theater. I currently have Studio 20's, a PS-1000 sub, CC-470, ADP-370's. The speakers are powered via a Marantz SR-6200 receiver. The room is approx 14x21 with 9-16 foot vaulted ceiling. The room opens to a stairway and kitchen/dining room/family room. There are some partitions between the rooms, but essentially, the entire first floor is open. Currently depending upon where you stand, the sound especially bass is highly variable. I am considering the Studio 100 or 60. I've listened to both at a store and enjoyed both, but I fear that the 60 may not be sufficient even for music without a sub. I realize the sub I have may not be the best for music. Any suggestions within reasonable prices? The music would be listened to in two channel, movies in DTS/surround sound. I have the opportunity to trade in the sub and 20's toward the 100's. Are the 100's by themselves fine for music and for the sound effects (explosions, etc) of home theater? That would free up floor space, which my wife would appreciate.

One final question: for bass management would the 100's or 60's be set "large" so only LFE (what Hz?) goes to the sub or should they be "small" so bass below approx 100 Hz be sent to the sub? The sub is connected via the receive sub line out.

I apologize for the long posting. Thanks in advance,

Brian
