It's a "first watt" concept for my tastes. Having owned a lot of powerful amps I've joined the cult of Single Ended esoterica. Efficient speakers (99db) and a little gem of a SEP amp (Firebottle HO...it's a HO) from Dennis Had performs brilliantly, far better than any mega watt amp I've owned. I do use high power amps (between powered subs, speakers, and passive speakers using high powered amps you get well into thousand of watts even for small-ish rooms) in live sound work as I like the headroom they provide.
