Best power tubes for a CJ premier 11A

I just brought a minty CJ premier 11A power amp home. It came with gold lion KT-88 power tubes with about 100 hours on them. Curious as to any other recommendations on power tubes. Will the 11 handle KT120’s?
i had a SF power two many moons ago and liked the Svetlana winged C 6550’s a lot. Thoughts? Rest of the system is a SF SFL-1 signature preamp, B&W 803 S speakers, CAL CL-15 CD player and rega planar 25 TT. Wiring is musica Bella emberglow speaker and IC.
Thanks for your input!
