Now you're sounding like the FTC test. Lots of inadequately heat-sinked amps will flunk the 1/3 power "preconditioning" aspect of the FTC test because the amps' thermal protection will kick in. (I still think its flaky that UL will certify an amp that does not work to their specification on the great bulk of the speakers out there -- i.e. 8 and 4 ohm nominal speakers. That's almost as good as the sun visor stickers that every SUV manufacturer now includes that say, in essence: This vehicle handles funny; watch out!)I really would like to know the details about the UL test; it must be fairly recent. I'm just too cheap to pay for the whole thing off their website. Thanks.
The FTC test originated in the 1970s because the IHF (Institute of High Fidelity) test was such meaningless b.s.
