TAD-60 owners, what tubes are you using?

Hello, just wondering what you guys are using for your TAD-60 and how are the results?

Currently I'm using Sino KT88, JJ ECC83, and EH 12BH7. Very satisfied with the sound but looking to try something different/better.
I recently sold my TAD 60. For power I had run Svetlana EL34s, SED Wing C EL34s, Valve Art KT88's, and Shuguang KT100's. All were very good except for the Svetlanas which are merely average. I was running Raytheon 5814's (to the best of my recollection) and JJ ECC83 for driver/pi.
