I've been pairing the GS-X Mini with the Audeze MM-500 for about a week. The short version: it finally let the MM-500 be what it's supposed to be. Three things changed immediately. The low-frequency range opened up in a way that had nothing to do with EQ — not "more bass," but deeper, more authoritative bass with real weight behind it. The soundstage expanded in both width and depth. And everything had more substance. As a recording engineer, I'm wary of gear that flatters rather than reveals. The GS-X Mini doesn't add color — it removes the ceiling. The MM-500 is a demanding headphone. Give it what it needs, and it delivers accordingly.

Fast shipping and great customer service
