...found them disappointing.
Thank you for the conformation, I just thought I hadn't found the right cobination yet, looks like I have a bag of expensive CCS's
Part of the disappointment...
Before plowing on further, I have to ask - If you don't mind, what was the other part?
The ones I have are United Silicon Carbide UJ3N065080K3S

I should be more precise.
AFAIK the UJN parts are reliable, but the linear performance of the ones
I tested was not particularly good.
The Cascode parts from Transphorm failed at 24V/2A, and looking at the
data sheet I did not see a DC SOA figure, only switching.
A similar issues have come up with some high power "hockey puck" power
transistors, referred to as "electrothermal instability".
So for starters I recommend being careful of parts that don't have a DC
figure on their SOA curves. The rest is just about whether they show
decently low distortion in audio use.

Hello everyone,
UnitedSiC has some quite new JFETS on offer (and the older UJN120xK discontinued), see SiC JFETs | United Silicon Carbide Inc.. I'm looking at the UJ3N065025K3S, a 650V/25mOhm SiC JFET which may be had for ~40 USD at Mouser. It has "a DC
figure on their SOA curve".
Anyone have an opinion on these? Thank you.

I chose the UJ3N065080K3S, easier to drive and not as wild - check pages 3 & 4 of the datasheets; also about half the price.
