You need 10 times the power to get a perceived doubling of volume...all elese being equal. In other words a true 100Watt amp will be twice as loud as a 10Watt amp. Doubling the amps power gives a 3db increase...which is barely noticeable.
This is why you often hear people claim their 30 Watt tube amp can rattle walls just as well as some receiver at 100 Watts. The reason is that most of those 100Watt receiver claims are totally fictitious. Most rate their amps at peaks or at 1Khz only. My rule of thumb with receivers was simply take their number and divide by two.
