Linear PSs are not noisy as far as I know. You're comparing apples and
oranges!! ;-))

Another vote for the Astron Power Supplies they work well.
Use the shortest run between the PS and radio you can and of a heavy gauge wire.

The Astrons are quiet and pretty reliable. I have had a RS20 since 1980
and the only problem I had was cured by replacing the regulator chip
about 35 years ago.

I have an Astron RS35 power Supply purchased in 1991. There was a period where
I didn’t use it for ten years. Now it’s in use daily and so far it continues
to be totally quiet.

I have several Power Werx switchers and prefer them for their size over the
heavy analog supplies. Fans are not a problem (actually, I hear nothing from
them at all) - IF you design your radio desk for proper equipment placement.
Place the power supply at your right hand - and you WILL hear noise, XFMR, fan,
etc.
It is amazing what proper station design/construction can do for making
silence. Open faced metal shelving and bare desktops don't cut it.
Just for grins, I put one of those Nanoxia fans in my IC-7300 and silenced it
completely. Worth the few dollars and effort. No temperature changes noted.
Hmmm - KPA500?????
