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.

The Sugden Signature A21se is an awesome amp. It lacks the bells and whistles of the others, but sounds heavenly. Besides, it is the original class A solid state amp, the one that started it all back in 1967. At $3250, it’s a bargain. 30 watts into 8 ohms/40 watts into 4 ohms, plus a larger power supply. If you can’t forgo the pretty VU meters, then buy a seperate VU meter such as the One little bear & Douk Audio, model vu1, off of eBay. It’s a great little VU meter for 50 bucks....you don't even have to wire it in, as it has a built in microphone, pretty neat.

Sugden Signature A21se was indeed on top of my list of amps to consider until I discovered the cost now is $3750 from the dealer covers my area, a $500 jump from the 2020 price, then I decided to look at other possibilities.

Luxman or Pass appears to be more capable in the lower impedance (4 ohm) region, although more costly, but appear to be a better selection.

Meanwhile, I am still hoping to check out other amps that is capable to provide 20-30W per channel of class-A output.

I have heard a lot of plausible hype from Coda folks. I nearly went that route but decided Pass had resale and Coda? Well probably not so much.

Luxman is out in my opinion. 

Compared Sudgen to Pass. No comparison-Pass much better.

Some nice Nazi gear out there. I prefer my service in the USA.
