Oh, I also cannot comment on the Sony EX1000s or the AHA-120 or SR71A...
Sorry, but I've never used any of those. I can give comparisons to the Fiio E9/11 or the Audioquest Dragonfly. Or how it sounds with my Vsonics or HiFiMANs. I wish I could be more help, but this is my first "high-end" amp.
I will say that I love it completely so far. I was skeptical about spending $300 on an amp, but I don't regret it at all.
