Step by step. Love what the Townshend isolation on both the speakers and TT has done to enhance the detail and soundstage. Recently added the Decware Phono pre and bass traps to the front wall.
I have the exact same speaker setup: Walnut Klipsch Belles (sans the PWK provenance) on Townshend seismic isolation bars (positioned, like yours, the only way they'll fit!). However, you've got the much nicer (upgraded) crossovers; I have the Crites "gold" AB replacements. Would respectfully disagree with the prior post re: subs. I've always run a sub with my Belles - and recently upgraded to a pair of Rhythmik F12SE servo subwoofers which, with the crossovers set to ~70Hz, sound very nice (subtle and well-integrated - not at all dominant). Placement proved to be a little tricky, but you can definitely tell when they're not there. Just food for thought. Thanks for sharing!
