Amazon put this brand new Onkyo receiver on sale for $379.99, I've been waiting for a 7.1 receiver to go on sale. This receiver has all the inputs/outputs i need, I was just wondering is 80 watts per channel ok? That seems kind of low and i was considering using the receiver to power the tsi100s, CS10, and some OWM3s. Is this enough wattage considering those speakers recommended power is 20-100 or so? I don't want to blow my new speakers!
