First off, my backround is electronics engineering technology. I have quite an interest in anything electrical and audio realted.
Test methods to determine audio power ratings are not the same between mfg's. In many cases the published wattage figures are done using the most favorable test method conceivable and is usually expressed in 'peak watts'. Any amplifier can produce 2-3 times it's normal power by overdriving it and recording the millisecond of peak power it produces... and all the heavy audio distortion that goes with it.
The correct way to measure audio amplifier power is RMS watts with the frequency the test was performed at and amount of distortion at that power rating. These ratings are rare to find, usually only higher end home audio, or some older 'vintage' equipment have them.
Ooooo I see. I'm a musician/audio engineer. Watts mean a different thing for me and there's a huge difference between 50 and 70 watts when it comes to a guitar amplifier. Granted, we're talking two different aspects of audio, but the idea remains the same.
I do not contest your statement, as I said, I was intrigued by it.
Unless you're an audiophile, watts don't really mean all that much. But if you are, well, stock systems just don't cut it.
