Hello Listening99. Power is a funny thing. The numbers don't fit into our brains very well. If you've watched Vu meters while music is playing, you know a 10 db jump is not all that impressive. The loudness difference between 1/10 of a watt and 1 watt is the same difference as between 80 watts and 800 watts! So 300 watts is not nearly four times louder than 80 watts. It's just under 6 db louder. 320 watts would be 6 db louder than 80 watts. So it's NOT a matter of perceivable loudness, it's a matter of the apparent ease of an hi wattage amp not running out of power and clipping at say, 200 watts when an 80 watter would have run our of power and clipped the wave, which sounds bad. A current hungry speaker (low impedance) is going to tax any amp, so it's good to have one that can deliver the goods when needed. Good luck with the new amps they will play cleaner at volumes where the 80 watter was struggling. Place them where they can have plenty of ventilation. Keep Smiling!
