Brianmgrarcom,
Unfortunately, there is no standard procedure to determine this! Nothing in the spec will show you this either!
It will be determined by the listener him/herself. If the store you are auditioning the B&W has a number of amp brands try on the smaller ones & then some of the bigger ones. You will hear the sound diff. The bigger amps will lend more authority & weight to the sound + they will sound "right".
All these terms are fuzzy & each person's ear is diff. so the definition of "authority", "right" is all subjective & I cannot exactly define these for you. I can tell you that the bigger amps sound much better w/ B&W.
Sorry for such a non-commital answer! It's very subjective.
