What folks would that be?Unfortunately, accessing the UL standard would cost me $400. But, I am curious, since UL is concerned with safety, not performance issues, as to why the UL test is "unfair" to receivers driving 4 ohm speakers.
Is it because the receivers burst into flames when delivering 1/3 rated power into 4 ohms (1/3 power usually places maximum thermal stress on a transistor amp)?
Or is it that parts of the receiver get dangerously hot under those conditions?
It seems odd that UL would permit equipment to be certified safe for use with less than all of the speakers that are out there -- and, let's face it, 4 ohm speakers are hardly unusual.
