Yeah, its a way of the companies to say that they have 1400 watts PMPO. average person things WOW. Big deal.
Real companies dont use PMPO they use dynamic power, such as NAD which can be helpfull in showing you what an amplifier can really do. Such as this: taken from the NAD site.
IHF dynamic power (max short term power/channel)
8 ohms 210W (23.2dBW)
4 ohms 340W (25.3dBW)
2 ohms 450W (26.5dBW)
Another thing that can be used to determine an amplifiers power is headroom. This isint displayed on those mass market junk because they probbly dont have any!
Taken from NAD site.
IHF dynamic headroom at 8 ohms 3dB
if you will read this months Axioms Audiofile newsletter you will also see what that means.
