Recommendation for Class-A integrated amp


I am looking for a SS Class-A integrated amp that is in 20 to 40W range, the short list I have so far are:

Sugden A21SE
Pass INT25
Luxman L-590AXII

Are there more you would recommend to check into?

TIA for any inputs.

Let me give some more props for the CODA. I now have the latest CODA 07x preamp and CODA #8 amp. I moved up from the CSiB integrated which I bought on A'gon used.

This gear is stuff I will never be selling. I think this 07x + #8 combo is good as the Luxman c900u preamp and m900u amp that I was so gaga about a few years ago. Luckily I could not afford them back then.

BTW - I bought the brand spanking new CODA from a CA dealer for a combined $11K. I also had some custom work done on the amp which added to the cost and likely killed any chance of resale (which I have no interest to do). So the guy buying used CODA pair for $6K sounds about right to me.
If you would love class A sound without the heat check out the new Technics integrated, based on GaN technology
OP - I am biased - but give the new Krell K300i a listen - uses new patent pending ‘sliding bias’ to stay in Class A longer. Pushes my Maggie 1.7i to new levels of clarity. If it can handle Maggie’s - any other speaker is a piece of cake. New the integrated runs $7k. Not cheap but build quality is great.
Went to demo and buy the luxman s and was left wanting.   Bought the Esoteric F03 with a milks discount but way over my initial budget.  Have no interest in resale as it has been the most enjoyable amp I’ve owned
CODA vs Krell vs PASS - one opinion:

OP: All three contenders on your list are excellent amplifiers in their own right
OP: it's more a matter of personal sonic and feature preferences rather than one performing better than another.
