FWIW I heard from my DAC dealer that had one for a week. Improved transformers, Clocks designed by Esoteric. Some upgraded caps. 7% bump over Terminator 15th -"his opinion" He will have another one in his system soon I guess. Cost is between $8-9 K. I have the Terminator 15th and I am very happy with it. No need for me to change for $3000 more.
