Power JFETs


What characteristics would make for a good power JFET?

I've been talking over at diyaudio about them. You really couldn't use them in a class AB amp because they don't have complimentary parts. They're all N channel. With thier power rating though they'd make for great ouput followers in a beastly single ended amp of some sort. Think SET with a 50 watts rating. 
A unity gain power buffer!!  Yeah, they could sure work for that!
As for the AB amplifier, remember Vacuum tubes are only N channel equivalents, there is no such thing as a P channel vacuum tubes!  It wouldn't be a complimentary symmetrical design but it would be Class AB.

@erik_squires4:  Actually, the V-I characteristics define the devices distortion and bias point.   Loop feedback may drive distortion down to low levels but the initial distortion is caused by the non linearity in the device itself.  All devices are non linear to some degree, some far worse than others.  
Have you seen the new Korg nutube triodes? They're through-hole mounted low voltage devices, two to a package. I think pairing those up with some power JFET outputs would be real nifty!
