Korg HA-S

After the NT-S1, KORG Expands Its DIY Range with an Audiophile Approach

With the Nu:Tekt HA-S, KORG continues the spirit initiated by the NT-S1: offering products to assemble yourself, without unnecessary complexity, but with a true sonic ambition. While the NT-S1 was mainly aimed at creators seeking a compact and expandable instrument, the HA-S positions itself as an entry point to quality listening and monitoring, focusing on headphone amplification and musicality. This continuity in the DIY philosophy allows for a different kind of equipment: understanding what you use and achieving a high-end result in a very accessible format.

A Headphone Amp for Sound Lovers, from Home Studio to Hi-Fi Listening

The KORG Nu:Tekt HA-S is aimed at those who want to get the best out of their headphones, whether to listen to music with superior detail or to work in a home studio with higher-quality amplification. It is particularly suitable for users who alternate between needs for transparency (balance, precision, respect for transients) and desires for color (texture, density, harmony) depending on the music, the headphones, or the time of day.

Its compact size and energy-efficient design also make it a practical companion: easy to integrate on a desk, near an audio interface, a player, or a hi-fi setup, without turning the workspace into a technical rack. And since it is a solderless DIY kit, the experience begins right from assembly: a real pleasure for the curious, enthusiasts, and anyone who likes to understand the signal path.

Integrated NuTube: Warmth on Demand Without Sacrificing Precision

Two Modes, Two Sonic Aesthetics

The HA-S offers a simple and effective approach: you choose the signature that suits your listening. In pure sound mode, the goal is fidelity: a clean, transparent reproduction, ideal for evaluating a mix, checking spectral balance, or enjoying headphones with a neutral sound. In tube sound mode, the integrated NuTube adds a more organic dimension, with a sense of depth and harmonic richness reminiscent of the pleasure of traditional tube amplifiers.

A Compact Technology Designed for Modern Use

The NuTube brings the "tube" spirit in a modern format: compact, practical, and suited for daily use. Combined with an energy-efficient design, it aims for an excellent compromise between sonic character and easy integration into a modern setup. The result: a headphone amplifier that remains discreet on the desk while offering real personality when you decide to activate the color.

The DIY Experience: Simple, Rewarding, No Soldering Iron Needed

Solderless assembly is an integral part of the Nu:Tekt concept: you assemble, understand, and enjoy. The absence of a soldering iron greatly lowers the entry barriers and makes the product relevant for a first DIY project. It is also a good way to approach audio differently, creating a more direct connection with your gear and giving meaning to every listening session.
