Thiel Owners

R. I. P. Dr. John. 

Hi Everyone,  Very much enjoying that this thread is so active. I've mentioned before that I own a pair of CS5's and CS7.2's.  The CS5's are close to mint, and the CS7.2's unfortunately have seen better days cosmetically. 
  When I originally started researching Thiel speakers, the CS5's were on my dream list.  Once I finally found a pair locally, it was a packaged deal with a pair of CS7.2's that needed work.  After sending the damaged CS7.2 woofers to Rob Gillum for complete rebuilds, the speakers sound great despite being cosmetically challenged.  At some point, I need to decide between the two speaker pairs on which to keep.  I've started A/B'ing them, and one thing that stands out is that the CS5's seem to be bass shy compared to the CS7.2's.  I am using the same amp on both (Levinson 436 monoblocks), they should have plenty of power. 
  So, my question is should this be expected, or should I be looking into the CS5's for issues?
