Thiel cs2.4 upgrade to cs 2.4 se

After much research and consideration, Tom Thiel has settled on Clarity CSAs for the upgrade. He even has a custom low voltage version to replace the electrolytics. I am going to also try Multicap RTX bypasses (1%) on the coax board. Progress on my 2.4s has been slower than envisioned last spring but I hope to have one channel done by the end of the month.

The passive radiator is hardier than it looks, but not easy to get the proper angle for removal. Pretty snug in there.

The (still growing) improvements ain't small to say the least!!

Lots more air
More precise pinpoint 
More fluent
Less grainy (it wasn't but .....)
More micro detail without any added  sharpness 
Impossible to locate the loudspeakers if you close your eyes 

Knowing me, in the end I will probably upgrade the whole crossover, but the big one will be for sure the capacitors I just did!!

I think the decision probably comes down to cost/performance ratio.  If you were to do the upgrading yourself, I would highly recommend something like Mundorf Supreme or some of Jantzen high end caps.

My guess is the electrolytics caps are in the shunt signal path so it may not be critical.  Also, they tend to be of very high value (like 50uf or 100uf higher).  So it may be expensive to replace them with poly cap.  For example, a 100uf Clarity CSA cap is about $100 dollars.
