Manual says the F5 will drive 2ohm

If F5 is driving a ribbon tweeter, I suppose even lower impedance will be ok, but how low is safe....will 1ohm be ok if only the tweeter is that low ?

It will drive these impedances, but I really don't recommend
them. If you want to drive a 1 ohm ribbon, it's best to work
on a design specifically tailored to that.

This is not very difficult, it simply means lower voltages and
higher currents.

I'm confused now, my liquid nitrogen cooled F5 runs fine into fractions of an ohm...?

Mount any Class A amplifier on a block of dry ice for superior performance.

Guys,
I have been seriously considering Magnepans for years now. Making the jump from my efficient 'run them on any amp' speakers to 'run them on only high power amp' speakers narrows the possibilities a lot. Any suggestions for a Pass amp that can really move these beasts?
