KT88'S for Rogue Cronus Dark

Thinking about going with KT88 tubes when I have my Cronus Magnum upgraded to Dark. I biamp my speakers so the Rogue powers the mid woofer and tweeter only.

Has anyone tried the Psvane Treasure or Psvane Classic KT88 and if so, some thoughts on these two?

Also, in another price class, any thoughts on the Sophia Blue Glass KT88's?
