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?

My Krell which is a class a/b amp runs class a for 50w and my Vandersteens are 86db/1 w. Not being a headbanger with the volume control and with the size of my room I don't believe the amp has ever run above that point. I like the Pass Aleph 5 class a at 60w and those are below $2000 and should work great with your Dalis.
" Here's a pair of Aleph 2 monoblocks for $1,100"

Are you sure those amps are not counterfeit or prototypes? I had most of the Aleph's and none of them looked like the ones in the pic's.

After reading that, I just wanted to update my post. An odd thing about the Aleph series is how they rate the 0s that I recommended above, and the 5. The 5's are 60 wpc and the 0s is 40 wpc (Not to be confused with the 0's which are the mono versions of the 0s's. 80 watts per mono).

The 0s is a much bigger, costly and more powerful amp than the 5. I have no idea why they would rate it for less power. Its just something to be aware of.
