I had a wonderful experience several years ago, dealing directly with Mark
and Nick at Rogue Audio. With their guidance and thoughtful advice, I
swapped out all the tubes in my non-Magnum Cronus, and the sound of
music has been sublime. I replaced the original Svetlana EL-34's with a
beautiful matched quad of Genelex Gold Lion KT-77's.

The five small tubes were replaced as follows :
an RCA NOS 5814 to replace the EH 12AU7 gain stage tube, a pair of GE
NOS Five Star 5751 "goldpins" to replace the Sovtek 12AX7 input
tubes, and a pair of GE NOS 12AU7A's to replace the EH 12AU7 driver
tubes. Definite improvement !! I'm not sure how to describe it, other than
saying the music simply sounds better.
Hi Bajead ..... $ 212 for the five small tubes, and $ 156 for the Gold Lion quad (both prices including shipping with secure bubble wrap and styrofoam packing.) To my ears, in my room, with my system, it was a very worthwhile investment. The new tubes brought the quality of my Cronus to a whole new level of refinement. Now that I'm thinking about it and actually sitting at my computer keyboard , I can describe the improvement as a more refined texture and tone, with more truthful musical timbre, tighter and deeper bass, an absolutely smooth liquid mid-range, and a sparkling non-fatiguing top end. A truly beautiful sound of music.
