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.)

Catman you are correct the Magnum version supports use of the KT90s.

Adam what signal tubes are you using?

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

I use the KT90s in my Magnum version, so take this for what it is worth , might want to try the Black Trasure 6CA7 in place of the EL34/KT77 - I sawpped a quad of BT KT88s in my Ayon Spirit 2 in place of the very good Gold Lion Reissues and they took the sound up a several notches - don't know if their 6CA7s would have a similar effect
