You can probably keep your current Axiom setup for HT and get another, dedicated 2 channel system ;-) in the living room, your studio, or whenever you listen to music most.
I saw you had B&W 704s in your list. I had the chance to listen to 703s (a little more expensive than 704s). Sounded great for me! I really suggest you should have a listen if you can afford them. You may add Paradigm Studio 100 V3, and Totem Forrest in your list. Please keep us informed what you got, and as I suggested above: keep your Axioms as well!!!!!
