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.
