The Craftsmanship

A desktop-friendly one-box configuration helps GS-X mini fit conveniently into your home or office. HeadAmp's fastidious dedication to quality, fit, and finish make it a piece that retains its beauty through its long life of service.  The characteristic colored front panels well-known from our Blue Hawaii SE and GS-X mk2 are available on GS-X mini allowing your choice of custom flourish.

The Story

Built using a special variation on our well-reviewed class-A audio circuit from the GS-X mk2 - based on the famous dual-differential design by Kevin Gilmore - the new GS-X mini is the first HeadAmp product to deliver balanced headphone drive from all audio sources, single-ended, or balanced.  This means no more compromising your headphone experience when using a single-ended source, your high-end headphones will always benefit from the speed and power of balanced drive when connected to the GS-X Mini.

Now paired with a custom discrete power supply based on the Golden Reference Low Voltage design, the Mini can out put up to 6W making the GS-X mini a great pairing with most medium-to-low sensitivity headphones, and high impedance headphones, whose sound comes alive when given balanced drive and higher power. Models like the Sennheiser HD800S, HIFIMAN HE-1000SE, Audeze LCD-5 all benefit from the clean, steady power delivery just as well as with easier to drive headphones like the Dan Clark Audio Ether series, Audeze LCD-X, and HIFIMAN Ananda. With balanced drive from any source, even single-ended ones, there's no excuse not to give your high-end headphones the power they crave, by connecting them to the new GS-X Mini.
