@avanti1960 thanks for your thoughts. Your experience with the RP-7 is interesting and vastly different from mine. As I mentioned, I've done extensive tube rolling in the pre and have also done so in my amps. I have a an NOS Telefunken in the 12ax7 position and rca cleartops in the 12au7 slots. Additionally, since my speakers have a built in sub and didn't need all the power from the KT120s and after speaking with Mark at Rogue, I switched to JJ KT88s. I really like the slightly warmer sound they provided without losing clarity.
Im sure I can track down a pair of amperex 12ax7 from Jesse but am a bit surprised you think that's where the money might be.
Thanks everyone for all the feedback! It's giving me a lot to think about! Keep it coming!
