Preamp output MOSFETs

Hey DIYA
Is there any MOSFET's in production today in TO220 packed that is particular popular as outputs in a preamp?

My knowledge of these is quite limited, but might try to design my own preamp in the near future.
My preamp now is Acurus LS11 modded to a state where I need to move forward towards something else. I found much inspiration from the Aragon lineup (28K and Aurum for example) with their enhanced MOSFET.

Regards
 
I'm not at all a specialist in electronics. If I end up trying to build a preamp it would be pretty much like the Aragon 28K or similar. The Aragon uses massive outputs, and it's overkill. Nevertheless it's better then the JFET's in the cheaper Acurus I own now. It really could use some headroom for improvement.
I've looked at the IRF610/9610 and they really are used in quite some descent pre's..
I've bought the Wolverine EF3-4 poweramplifier boards (I build it with 10k input) here on DIYAudio and stating the build around Jan2024, then maby a new DIY preamp for my Living room afterwards.
 
Here's Aragon 28K; TO220's at Q7/Q8
