Yes he has that horn now and also has changed his transformer to nanocrystalline. Plus, some of the videos I linked were without the DaVa and the Melco, so his analog is better now. He has one driver less now (TAD 2002 is gone with 4003 covering the entire range from 550 hz up). He is also experimenting with DRC from 550.
But imo all that is voicing. When you have a good horn speaker that does 110 db till 75 hz, then the bass horn does 100 @ 30 and 92 @ 15, you can pur nano or superpermalloy transformer, 300b or GM70, 2a3, 845, 211, EL84 push pull, EIMAC tubes, lamm, kondo, NAF, mastersound, roll tubes to your liking, and it will all excel for all genres of music.
