Nice system! In every system I have heard that has a TV screen between the main (2-ch, music) speakers, the music-only-listening has improved dramatically by covering the TV screen with removable acoustic panels or a large, thick quilt--or something like that. Just cover the TV when you listen to music-only. Try it.
BTW, I have a soft spot for Jadis amps. Never heard one I didn't like. Also, a well-executed smaller, two-way based system is often easier to get to sound coherent than a larger, multi-way one with bass loading/standing wave and driver-integration issues. Stick to your guns.
