I agree with Tpreaves.....Enjoy your new Cronus "as is" before you start rolling tubes. It sounds really, really good with the stock tubes. Then, once you have the desire to try new tubes, there are a lot of ways to go.
For me, my Cronus, being fed by my Rega P3-24/Exact 2/TTPSU and Rotel RCD-1072, through my Vandersteens, sounds better after I did the following : an RCA NOS 5814 to replace the center 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. I then replaced the original Svetlana EL-34's with a beautiful matched quad of Genelex Gold Lion KT-77's.
All this "tube rolling" was done after some pretty nice conversations with Mark and Nick at Rogue Audio, and I'm glad I followed their advice. They are a pleasure to work with.
Good Luck, and Happy Listening !
