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.

I utilize the KT90s on the SFS80 amplifier and it sounds fantastic. The bass is strong, the highs are good and the mids are almost perfect. My system consists of almost all tube based SF components. I use the SFS80 amp, SFL1 preamp, SFD1 DAC and finally the SFT1 transport. The Canton 807DC speakers I'm using are bi-wired and not the most efficient at 88SPL but still sound quite nice at mid volume listening levels. I have a spare set of 6550 and they're not bad but not as good as the 90s. Only problem, the KT90s are becoming more difficult to find and the price continues to climb.
