HeadAmp GS-X Mini Balanced Headphone Amplifier/Pre-Amp

Feels perfect.

For context, I have previously owned a TA-26, Asgard 3, and an RNHP. My experience with this amp thus far is that it is the most transparent, revealing, and dynamic amp I’ve ever had. It highlights bad recordings and absolutely celebrates the good ones. Totally is feels perfectly balanced/neutral: nothing is exaggerated. And gobs of power :) Would absolutely recommend. (Using with HD650 and DT 770).

The MM-500 Finally Has Room to Breathe

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.

Superb. . Full Stop.

Awesome reference quality.
