Alsyvox speakers and low powered amps..a new day?

At the recent Munich show, the panel speaker manufacturer Alsyvox demo’ed their new large Raffaello with a lower powered Jadis amp. This amp is one I am intimately familiar with, the Jadis JA30mk 2 which puts out 48 watts/ch with the supplied KT150 tubes ( not 30 watts as has been erroneously reported). 
Anyone here have a chance to hear this pairing? Apparently to some it was the best sound at the show, and demonstrated that a large panel speaker, if efficient enough, can indeed work great with a lower powered tube amp.

The days of only being able to power panel speakers with monster ss powered amps are over…hopefully.
