Low power tube amp for Sonus Faber?


I'm thinking of buying an Italian tube integrated Mastersound 845 compact for my SF Elipsa SE. 
It uses 2 845 Valves, single ended at 30W per Channel. Would really like to try a valve amp on the Elipsa. Is this a mistake? Has anyone tried this? I've listened to Mastersound pf100 which are 120W mono blocks and I was blown away. Unfortunately the price difference is nearly ten fold. Has anyone tried using a low power valve amp with SF?

I bet that amp will never get out of 2nd gear in a small room even with the SF speakers, and it's doubtful you will ever use up the 30 watts unless you use your room for drunken dance festivals...30 single ended watts is a strong wallop of mojo. I initially used my 12WPC Dennis Had SEP amp with allegedly 91db speakers (they may have actually been closer to 89db based on Stereophile measurements) in a largish room, and the preamp (SS with lots of gain) had enough gain to drive the amp into clipping which I only did when wondering, "what does this amp sound like when clipping?" Music could be plenty loud well below the clipping point so I just enjoyed the crap out of the rig...switched to 99db speakers eventually (Klipsch Heresy III) which really are more appropriate for this amp, and use a lower output tube preamp. Now things can get way louder than I ever want it to with absolute clarity, well under the clipping zone.
