[QUOTE="trumpet, post: 8329794, member: 628688"] I stay out of the amplifier "clamping" scene as it's not a technique I use as either as a salesman or a technician, but it's a fact that Volt-Amps are not equivalent to watts. I recognize that forum folks like to compare clamp test results, and it has been argued that since it's more or less the standard then there is some use for that test. That said, I can't ignore scientific fact because it's the entire basis of audio reproduction.

In other words, it's an arbitrary figure they state as an assumption that with music playing the amplifier may be able to make that power momentarily. In other words, it's a peak power rating. I don't agree with it as I'd rather see power ratings measured and published something like the pro audio industry tends to do. A "Program Power" rating makes more sense than RMS. [/QUOTE]
