Best tubes for Sonic Frontiers 80

Hello,
My amp is a Sonic Frontiers 80 (in stereo) and I am wondering what would be the best power tubes for this piece of equiptment. Currently on this site there is two pair of Ei- KT90 for a fair price.As of now I am running EH KT-90 which sound fine but as we are aware of we must search for the holy grail. Excluding Gold Lion for
price,(KT-88) what would be my best power tubes for my amp? This amp can take, EL-34.KT-88, KT-90 & 99.
Thanks for all the help.

By far my favorite tube in the SFS-80 was the Ei KT-90 Type 3 tubes. - Make certain to give them 400 hours (not an hour less) to open up and gain the liquid midrange.

Coupled with some nice NOS Bugle Boy input tubes or Tele Diamond base, etc. this amp will sing!

Good luck on your search.
