The GS-X Mk2 is HeadAmp’s flagship amplifier for dynamic and planar magnetic headphones. With a circuit that has evolved and matured over a 15-year period, the GS-X Mk2 is the most powerful, linear, and transparent amplifier that we have ever produced. Pushing up to 6W of class-A power into balanced headphones, the GS-X Mk2 can tame the toughest headphone loads on the market, while its’ low-noise circuitry delivers an equally brilliant performance with sensitive in-ear monitors.
In addition, the GS-X Mk2 makes a fine preamp for your stereo speaker system. With its’ high input impedance, low output impedance, multiple I/O options, 3-way gain control, and precise volume control, the GS-X Mk2 can fit into almost any stereo rig, and provide the same wonderfully transparent sound output that it does with headphones.
The GS-X Mk2 is a carefully handcrafted piece of audio equipment, with painstakingly matched components, and the highest standards for build quality in the business. Every GS-X Mk2 is tested extensively throughout the build process, as well as before, and after an extensive burn-in process to ensure the best possible performance.
As 0f January, 2017, all GS-X Mk2 ship with the DACT 24-step attenuator volume control.
Our Take
The GS-X Mk2 delivers the quickest, cleanest, most transparent sound you will find in a headphone amplifier, and does so regardless of the headphones you pair with it. You’ll simply hear the character of the headphones themselves, and the connected source, as the GS-X does its’ part to supply all the power your headphones need, without coloring the sound. The GS-X is carefully designed to provide the same level of experience whether listening with high sensitivity, multi-driver in-ear monitors, low-impedance current-hungry planar magnetic headphones, or low-efficiency, high-impedance headphones. The combination of extra low-noise transistors, careful part matching, and an adaptable gain setting work together to give your entire collection of headphones just what they demand.
