How much power needed to drive 91db speakers?


Sonus Farber lists the sensitivity of my speakers at 91 db SPL@ 1 meter @4 ohms.  They also say I should use  50-450 watts of power. My PS Audio amps pump out 500 watts @4ohms, so the max isn’t a problem, but if I switched to something 15-50 class A watts, would that be more than enough power?  
 

Thanks in advance.

Sonus Faber speakers are a wolf in sheep's clothing. Starting with the mid-level models and up are very watts and current hungry but just as sensitive with electronics and cables. SF work very well with MAC gear and sounded sublime with Burmester.
