George, Anyway, it seems that the very nature of mosfets would make them especially suitable for low impedance loads, no?
Simply put NO, they will drive them but will run out of steam (current) at those loads below 2ohm, especially at the below 1ohm points discussed, BJT's (bi-polars) are for these speakers.
And I believe most Infinity's were voiced around Krells, as they were one of the only amps around at that time that could drive these sort of loads "with ease".
Cheers George
