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.

Mu buddy has the Luxman 595 and is a former owner of the 590 AXII. The difference in price is justified according to him. Here is the list of differences.
What we understand is that there are over 120 parts detail differences between the L-590aXII and L-595ASE;

* Different main power transformer, with special attention paid to noise entering the circuits. And with special vibration control of the transformer itself.
* New, special power supply capacitors. Also installed with special vibration control mounting.
* Anti-resonance chassis design elements implemented in the extreme.
* Peel coat PCB’s implemented where it can make a difference.
* Special copper clad critical signal path shielding.
* Special “Line-1 gold direct onto copper (KAPPA) alloy” RCA style input jacks. (For best sound quality)
* Special selected Nichicon and Nippon Chemi-Con capacitors used throughout.
* First introduction of Luxman’s proprietary “ODNF-u” (Only Distortion Negative Feedback – Ultimate) in an integrated amplifier application. (An advancement over ODNF 4.0)
* Special, very low -impedance speaker relays. (Higher damping factor= 370)

Problem with CODA (if you consider this a problem) is resale value. You’ll get crushed if you buy anywhere near MSRP. Coda has far fewer dealers than Luxman or Pass so you can get better discounts with LUX/PASS than you probably will with Coda. I have Coda 8 + 7 Pre-amp so Im certainly not a Coda basher. I bought the pair for around 6K combined with only 6-9 months of use on them when they were listed. Think the MSRP is 13-14K on the pair. OUCH!
Not easy to find these days but you could also consider a Kelvin Lab The Integrated.  I'd love to get my hands on one!
Take a close look at Stereophile’s measurements for the Pass:

At lower impedance (4ohms) distortion rises with higher frequencies. Something to consider.
You should not worried about
cOdas resale the brand is gaining a huge following and the fact that thete are next to 0 being sold used means their scarcity will keep the resale high and make selling a used one easy

These are all solid choices.  Regarding the Sudden $500 increase, don't know if it's justified or not, but my math is you will probably own a piece like that for 10 years.  $500/10 years is $50 per year for what you may want.

My philosophy.  Best of luck finding that dream integrated.
