You may want to add some mass to those stands (I kid, I kid ;-)
On interconnects, I've come to realize over the years that it's easy to pay big for diminishing returns. Also, what one person swears by is often unlistenable to another's ears. There may be no other component as subjectively praised/loathed as interconnects. Best of luck finding ICs that sound good to you in your system. FWIW, I've been through many, many cables (Nordost, Transparent, Anti-Cables, Kimber, AQ, Cardas, and on and on... I'm currently running a pair of balanced Reference cables from Morrow - and they sound just fine (to me).
May I ask why you are planning to migrate to Martin Logan CLX? I've been having the same thoughts lately (currently very much enjoying a pair of ML Summit X)... but I'm somewhat hung-up on that missing bottom-end of the CLX.
Cheers
