Oh come on George, I don’t know any amplifier vendor that publishes independent data, only reviewer data.When I say that it’s Stereophile, Miller Labs, Newport Test Labs ,ect ect and like that are independent that give you the truth. If you want to believe the BS many manufacturers give you that’s your problem.
As more and more these days the manufacturers are "grossly understating their 8ohm wattage" to make the the 4ohm look like it’s closer to doubling, same goes for the 4ohm to the 2ohm, and Stereophile test confirm it.
And if you don’t know this then you’ve been hiding under a rock, and can’t see the forest for the trees. But I already knew this.
It’s easy to drive into 2 ohms with complimentary MOSFETs.You will not get anywhere near the current performance what same amount of complimentary BJT’s can do into 2ohms. That’s why all the very best amps that deliver huge current into 2ohms are all BJT (bi-polar) again your under a rock
