Douk Audio P1 tube amp tube replacement/upgrade

Any good tubes to replace the stock ones on this amp? I have the GE JAN 5654W's in the amp. Anything better?

Presently I am using a matched pair of Russian 6ZH1P-EV tubes in my Douk Audio P1. I have also used a matched pair of the GE JAN 5654W tubes. I am not an audiophile. I think that the Russian tubes sound ever so slightly better than the GE tubes, yet the very slight difference is not worth the additional expense. I don't think that you will be able to significantly improve the P1's sound beyond what you are getting with the GE tubes. This is due to how the P1's circuit board is designed in terms of how the P1 operates the tubes, and because the P1's IC op amps are not user replaceable with better op amps.
