I have the Rogue Cronus Magnum which comes with the EH KT90s - I haven't heard any other KT 90s so I can't offer a comparison, but they sound fine with the NOS tubes I have in the front end.
Magnum, if the above reference is to new issue Gold Lion KT 90s please advise where you purchased these as I haven't seen them any where?
