I would seriously entertain a suggestion along these lines :I just feel that rating an amplifier at sine wave output is a bit unnecessary for a device designed to amplify music, not a high duty cycle tone. This article kind of sums it up, it's not directed at you but for others to paruse. I'm prettyy sure you know what I'm talking about.
Rail voltages at 200V and can be sustained for a few seconds max. But do they need to sustain any longer? That begs the question.
If you asked me about this 3 years ago I would have fought tooth and nail about the new rating system. I liked the "old iron amps." But after seeing the new breed of amplifier in action I can say that it really makes no difference, the new amps, say one that can make huge peak power but only sustain a fraction of that will SMOKE a similar amplifier that can sustain more then the newer ones. So yes a 5KW amp MAY be able to sustain 1KW but will chew an amp alive that can sustain 2KW when it comes down to the real deal. Pushing a bunch of 18's every time that kick drum hits.
It goes right along with the earlier thread of how much juice is REALLY getting pulled down those power leads to the boot.
"We know that any complex signal can be decompossed into nothing but a linear combination of sine waves, aka tones. But a single sinewave is not very representaive for two reasons :
1. Intermod distortion requires more than a single freqeuncy.
2. The crest factor (ratio of peak power to average power) of a single sinewave is not representative of music.
We recongize that amplifer design can "exploit" the crest factor of typical music, by storing sufficient amounts of internal energy. This may allow an amplifier to supply peak-bursts, for short periods of time, even though the long-term average power delivered is unaffected by internal energy storage.
Therefore we propose a test consisting of an industry-standard signal, somewhat more complex than a single sinewave, ...."
Know what i mean? First, demonstrate a mastery of simple engineerig concepts. Then, demonstrate why the new proposal is not just more marketing fluff, but real valubale stuff. Then, demonstrate that you're not just going to try to fool the consumer by inflating the results of the existing tests, just to sell your product. Finally, propose the new method.
And yes, i know, my criticisms are kinda aimed wildly ... at manufacturers as well as hobbyists!
