I wish they'd had this version earlier. I was not impressed with the regular Cronus with EL34 tubes.
The KT-120s are also a big step up in Rogue's M-180 monoblocks.
I've tried clear tops and bugle boys in the M-180s, but I've gone back to the Philips 12AU7s that the amps came with each time. (Perhaps I should order some backups while they are still cheap.)
On the other hand, the GE black plate 12AX7s (used from ebay) were a great success.
