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.)

A year later... the amp sounds absolutely wonderful with the Gold Lion KT-77's.
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
