3rd - Rob Gillum is the man!
He rebuilt my CS2.3 mid/highs in 2017. Now they 1) sound better than new especially the 3D soundstage, 2) are cured of any slight aggressiveness that Thiels may be criticised for and 3) were perfect straight out of the box with no running in required. I have auditioned several current $10,000 speakers and none of them come close to my Thiels. He can surely work magic on the woofers.
