what about a professional audio amp? I saw some at my local music store and they put out 200-250 watts per channel for only $299. Seems like a good deal. I know that it might not be high current, I dont know the exact specs (voltage and current) but for that price it seems like a good deal. what do you think? is there a difference between a pro audio amp and a regular audio amp besides the connections? Is clean power in one the same as the other?
