Rogue Cronus Magnum-2 years and never tube rolled

Are there any Cronus Magnum owners that could share some tube rolling information? I'm still running all factory original tubes and now that I have new Harbeth C7's I'd interested in rolling some tubes. I'm not even sure which one's I roll (I know not the KT90's) Any information greatly appreciated.
You posted this question not to long ago :
Don, did you check out any of the tubes the good folks suggested in your other thread? Just wondering. Good luck.
I think I'm going to check out Ei 12AX7 / ECC83's. I thought I might be able to pick up some information from more recent Cronus owners. I'm just trying to figure out where the best place to buy them is. I'm not as concerned about the lowest price but more reputation.

Sorry for the re-post. I tried to get the moderator to delete it with no luck.
Hi Donjr....... Yesterday you answered my posting to your original thread about this, and I'm glad I may have been of some help with my experiences. When I switched all five small tubes, I gought them directly from Rogue. With my EL-34 to KT-77 change, I worked with Very nice people with fair prices and high quality stock. Happy Listening.
