Chris, what type of circuit are you using these in? They sound pretty good!
Could you post a circuit diagram by any chance? Cheers.

I'll send you the schematic I use by email, though I'll have to get our
CAD guys at work to produce a .pdf file from the Cadstar schematic.

By the way, the BUZ900 and similar FETs work much better (in SPICE
simulations at least) in CFP output stages rather than in
source-follower output stages. For source-followers I would still use
high-transconductance FETs like IRL540 / IRL9540 if you can keep the dc
operating point well controlled.
