HEADPHONE AMPLIFIER The HA-S is a DIY (mount yourself) headphone amplifier kit equipped with Nutube, allowing you to enjoy the highest quality audio anywhere. No soldering is required, so even if you're new to the DIY world, you can mount the HA-S to easily add warm, analog valve-driven sound to any sound source!

Nutube is a revolutionary new fully analog valve developed by KORG INC. and Noritake Itron Corporation. Like a conventional valve, Nutube is constructed with an anode, grid, and filament, and functions as a full triode valve, effectively generating the response and the same rich harmonic characteristics as conventional valves in a more compact, stable, and energy efficient format. . The transparent cover of the HA-S offers an overview of this technology, allowing the valve glow to be visible at all times.

The Nutube filament is powered by a DC to DC converter, which consumes less electrical current and therefore allows longer battery life than other valve-equipped amplifiers. The design is so efficient that the HA-S can drive Nutube with a line voltage of 26V using only two AAA batteries, for a rich and authentic valve sound.

The HA-S has a special NFB (Negative Feedback) switch, allowing you to choose between clean, pristine, high-fidelity sound, or a warmer, more harmonically rich sound as expected from a valve.
When the NFB switch is off, the harmonics present in the Nutube (trio valve) will be amplified to create a sound rich in harmonics, warmth, and textures. When the NFB switch is on, the distortion ratio and frequency characteristics will change, creating a truly detailed and clean sound.

For further sound modification, we've included two OP amp options for the output: the premium audio 'MUSES01' and the industry standard 'NJM4580', both from JRC. These can easily be replaced so even the most purist audiophiles will be able to customize and tailor the sound of your HA-S to your preferences.

For advanced users who want to customize their amp even more, circuit diagrams are available, making it easy to change discrete components and customize your own unique headphone amp to suit your tone and performance preferences. The possibilities are endless!
