Best Class A Amp under $2,000 used?


Looking for a Class A Amp (USED) to join with a Wadia 321 DAC and Dali ms-4 speakers for digital sources.  Budget around $2,000.   What are some good possibilities in this range?

Part of my inspiration to move to solid state was a purchase of a Kenwood 700 M which I think sounds amazing compared to my ICE powered amp. I figured a modern solid state version would be even better.  The Threshold looks nice.

That Threshold "e" series was the last Nelson Pass design at Threshold. Also, the recent work on the amp was done by Jon Soderberg. He worked for Nelson Pass at Threshold, so there is no better Threshold tech anywhere.

Why did you want pure class A.  As all have said most amps are high biased to hold in class A until a threshold wattage requirement is surpassed then it operates in A/B. I have never been sure of when Class A resumes during a peak then drop .   I owned Klipsch Palladium 1Ks which were biased to class  A for 125 watts.  I never knew when it changed.  *not a great amp anyway!
I had no idea most class A type amps switch into alternate AB power after a set threshold. This is really cool though.  Just looking for advice on a great solid state choice in the 2k -  3k range.  So far Pass designs are king.  Let me know if there are any others. Bryston??
