I've never bothered, and never will. No offense, but people who want things measured are their own worst enemies. There never is any satisfying them. Not saying you are like that. But plenty are.
My last speakers were supposed to be 90 dB and they would play plenty loud. Whatever Moabs measure in dB is in a sense irrelevant. What matters is how they compare to other speakers. Whatever it is, its more than now, and so I am sure they'll play louder with the same amp than speakers that already play louder than I need. Whatever yours are, I would take the same approach, and anything around the same level you will be fine.
In case you don't know there are plenty of low watt SET amp owners saying their Moabs and Ulfs work just fine, and in bigger rooms than yours. So again you should be fine. Search around, you will see.
