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.

As others said, I have the last Coda 07x and the No 8 (v1) and the resale value is not a problem for me as definitely they are keepers. 10 years warranty is not bad either if you are the original buyer, 5 if you don't. 
@gubaface,

Thank you for the suggestion.



@georgehifi,

I am not familiar with Gryphon gear, could you describe further on how Diablo 120 sound compare to some of the Class-A integrated amps listed?
