People whose ears I trust swear by the LTA. I have their UL amp and it is simply amazing so I would not be surprised if the LTA is right up there with the best. I recently bought the new Herron VTSP 360 ESP. Fantastic linestage--significantly better than the already great VTSP 3A (RO3) and should be on anyone's list at $6.5K. Both the LTA and Herron are less that half of the OP's price point but I would venture are right up there with others on the list that retail $15K but to be fair I haven't heard them because I can't afford $15K!
