Gary, Fran... There is only ONE spec that matters worth a damn, and you will never find any small PA manufacturer using it.

THD@(x)db

Everything else is just bullsh*t...

How dirty does it sound as it gets loud? They all do, you know. Who cares how long the batteries last, who cares how many W RMS it is? For starters, neither of you use a battery powered arranger. If you've got AC for your arranger, you've got AC for your PA. And RMS is a meaningless stat, without the THD figures at that stated power, and the loudness (in db) that that power achieves.

Have fun ribbing each other, but shame on you! You BOTH know how insignificant what you are arguing about really is...
