I was supposed to try some of their tube monos a few years back and it never came about.
If you were referring to the Rogue Dragon Monoblocks, that is the Rogue product I am aiming at placing under my rack. Like the OP, I have a fair collection of 12au7's that I switch out in my RP-1. My plan is to upgrade to RP-3, but in doing so I discovered the Dragon Monoblocks, a hybrid amplifier that is Class D. So convenient. Kind of bridges the gap between no heat and the ability to change the sound of the amp - using one tube I already have.
In today's world, one is smart to stay local, or at least national. Rogue is located about 45 minutes from where I reside.
