Definitely explore tube rolling options; all the Rogue gear I've had -- past and present -- responds brilliantly to good swaps. The warm vintage stuff like Mullards and RCAs will likely be an improvement over any new production tubes, but Rogue gear tends to *really* take off with higher clarity/resolution/dynamics tubes like Telefunken and especially Mazda (especially chrome plate 12AX7 for those slots - WOW). Also, the 12BH7 is a great swap for the 12AU7, but ask Rogue first, as this tube draws twice the heater current (they've cleared it for my Apollos and Ares).
They're shipping RCA clear-top 12AU7 with their higher-line gear (e.g. Apollo Dark), which might be in your RP-7. A fine tube, BUT there's always a nicer 12BH7 out there, in my experience (tougher to find a quiet 12BH7, though). There's also a French chrome plate 12AU7 that's worth a shot.
