Watt Gives?


Why does 75 Belles Watts smoke 250 watts from Anthem, PS Audio and W4S?

Not only do the Belles 75 watts play equally as loud, but it has the best bass texture, grip and slam, openess and top end...

Is this a case of 160hp on a 400lb motorcycle surpassing a 600 horsepower 4500lb in terms of acceleration?

I’d like to go up the ladder but I guess up isn’t always directly related to specs?

Really starting to question analogue / high efficiency, low powered beastly tubes...

A few things are going on there. Power output is measured at frequency(s) and a distortion level. So not all amps are measured the same. Next is just one channel driven or all channels driven (usually just one). Next is the power supply, it may be fine for one channel and run out of steam with both channels driven hard. Third is that doubling the power only gives you a 3db increase so there’s not much difference between 75 watts and 150 watts.
