Rogue Audio Cronus &/or Atlas owners ... TUBES ?


My Rogue Audio Cronus integrated amp is about to reach its third birthday, and I'm ready to replace the original Svetlana EL-34 output tubes. What are your experiences and thoughts ? Stay with EL-34's ?, try Gold Lion KT-77's ?, perhaps EH KT-90's ? See my sysytem for the rest of my stuff. I mostly listen to 1950's - 1960's small ensemble jazz (tons of Blue Note re-issues, etc.)

They shipped my Magum with Sylvanias which were very nice sounding, but Ididsome tube rolling afterwardsand have Tungsol 5751s and RFT 12au7s - , theSylvanias were not bright but these have a slightly warmer sound which I prefer
A follow-up........ I replaced the original Svetlana EL-34's with a brand new matched quad of Genelex Gold Lion KT-77's. Absolutely beautiful.....My system has never sounded better !
A year later... the amp sounds absolutely wonderful with the Gold Lion KT-77's.
