The Big Ayon Triton KT-88 Int Amp- tube rolling?


I am quite pleased with the stock tubes, however am wondering if any Ayon Triton owners have tried anything other than the Gold Lion Re-issued KT-88's? As for the input tubes, how about the RCA 12au7's- tried anything else?

**And as a sidebar- as this is an integrated with Direct preamp input option, has anyone actually tried to add another preamp in front of it with good results?

Sutts, I have The Spirit 2 , but am using the RCA 12 au'7s and like them very much with the amp. Also I tried SED KT 88s will I was buring in some new speakers, but much prefer the Gold Lion's in this amp

David 2, I've had my Ayon Spirit 2 for several months, it is extremely well built, no tech issues at all, easy to bias, and holds bias well, very musical amp
Has anyone had experience with the monster kt120 tubes - adding more power and experiencing cleaner dynamics. I think this is in the test phase with Ayon but not shure.
I'm also using a Spirit II with no issues. Good bass for a tube amplifier I should add.
thanks guys- I do keep in touch with Paul at USA Tube Audio (Ayon Distributors) about this from time to time, and I do know that they are always 'on the hunt' for the best tube combo for the Ayon amps- they still recommend what was shipped with my Triton- the Gold Lion KT-88's and RCA 12au7's- no complaints here...
i have a friend who had the ayon spark and just loved the amperex 7316's in it.
