I'm looking for balanced SS headphone amp and these two got my interest. I think they both are slightly on the warm side of neutral which might suit my taste of tube-like SS amp yet fast & dynamic. 

 

Two things in similar:

- they are balanced

- they both use op-amps

 

Sound quality wise, I wish that the M3 is close to the Beta22's performance.

 

Any thoughts/advice guys?

Has anyone compared them?

 

Thanks in advance.
