Ted installed the whole enchilada (FEQ and XOTs). He also put HFTs on each of my Tranquility Bases (he even opened my Aurender unit and put 10 inside - on all HDDs and chipsets - although I no longer have the unit). All told, he used 8 boxes of HFTs.
The installation was done in stages with a perceived audible benefit at every additional stage. I found the ART system less beneficial with, to my surprise, the gang agreeing that it was not necessary in my room. I did get the Vibratron and one Bass Station however.
IMO, Synergistic Research does some unexplainable things but, as you can see from my sig, I'm sold, hook, line and sinker. The Galileo LE is amazing me at the moment and Ted's offered to zap all my Pass umbilical cords on his tesla coil. SR offers in-home demos; I can't recommend it enough.
