jafant,
Sadly I do not have a system setup. I'm keeping the CS 7.2 as with some effort they are tough to beat even in the 20-30k range.
The Pass Labs will stay as they mate very well with the Thiel's.
From my experience a tube pre amp is a worth while addition. I have a Supratek Grange Signature. You add that 300B mids while maintaining the sparkle on top and the solid bottom end with the Pass. The three are the best synergy I have experienced in a Thiel rig.
At the moment I am looking at DACS in the 10-15k range.
Cabling is a crap shoot. I have quite a few to choose from.
I'm hoping Tom takes the 7.2 crossover on. I want to make them external and replace the internal wiring.
I'm going to sell the CS6 and maybe the CS 2.4SE as my listening room is too large for them.
