Jadis Orchestra Reference - Best Tube ???

I just tweaked up my Jor and it sounds great.
I have been using Gold Lion KT88 reissues because I was told they are the best sounding. I am curious to hear other tubes in it and would like any recommendations.
KT90, KT88, EL34/6CA7, or anything better would be helpful.
I have a pair of Mazda Silver Anode 12ax7 nos tube in there right now also.
It sounds great but I want to see if it can sound even better.
Try the Shangwang Treasure KT-88'sAlan
This has been discussed pretty heavily before.
