ATH-3

Step-up transformer for MC cartridge

Step- up transformer for MC phono cartridge full of Air-Tight’s accumulated experience

The digital technology having been thoroughly investigated, ironical to say, now analog discs were revived in the form of ‘Renaissance in Audio’.

This step-up transformer is designed to be compact and easily handled.  Theoretically, to augment the signal level by transfo. Has advantage in terms of noise components, especially in case of today's affluent good MC cartridges of low impedance. Newly developed Hi-μcore is loaded in the transformer to realize the high step-up ratio of 1:40 (32dB gain).

To polish up the tonal performance pure copper transformer-holder, thick aluminium front panel and “monocoque” chassis are employed for enhancement of signal linearity and musical dynamics.

The ATH-3 boasting of high step-up ratio is suitable not only for vacuum tube phono equalizer amp but also for solid-state amp.

Intrinsic vivid and dynamic musical characteristics are thoroughly transmitted and reproduced through the ATH-3.

Why Choose Air Tight

Air Tight is one of Japan’s most revered valve amplifier manufacturers, renowned for producing beautifully handcrafted amplifiers that combine traditional Japanese craftsmanship with extraordinary musical refinement and engineering integrity. Founded by the late Atsushi Miura after his influential career at Luxman, Air Tight was created around a simple philosophy — build uncompromising valve electronics designed purely for musical realism and emotional engagement.

What makes Air Tight particularly distinctive is the company’s refusal to chase trends or mass production. Every amplifier is assembled in Japan using carefully selected transformers, premium internal components, point-to-point style construction techniques, and highly refined circuit topologies developed through extensive listening and engineering experience. The result is a range of amplifiers that feel timeless both sonically and physically.

At HeyNow Hi-Fi, Air Tight products represent some of the most emotionally captivating amplification available today. There is a naturalness, tonal beauty, and dimensional realism to the presentation that allows music to feel remarkably human and physically present within the listening space.

Signature Design and Sound

Manufactured entirely in Japan, Air Tight amplifiers are engineered around highly refined valve circuits and exceptional transformer design, with enormous attention paid to component quality, power supply stability, and signal purity. Unlike many modern products designed around specification targets or visual spectacle, Air Tight amplifiers are fundamentally voiced through long-term listening and musical coherence.

One of the defining characteristics of Air Tight amplifiers is their remarkable harmonic texture and spatial realism. Instruments and vocals are reproduced with convincing body, tonal density, and a highly holographic sense of dimensionality. Rather than sounding soft or overly romantic, Air Tight products balance warmth and refinement with excellent transient delicacy, low-level detail retrieval, and natural dynamic flow.

The company’s output transformer design plays a major role in this presentation. Air Tight transformers are exceptionally refined and contribute significantly to the amplifier’s sense of openness, tonal purity, and effortless musical communication. Combined with carefully implemented valve stages and substantial power supply engineering, the result is a sound that feels fluid, spacious, and deeply engaging without becoming overly coloured or slow.

Air Tight also remains highly respected for preserving the individuality of different valve types throughout the range. Whether using EL34, KT88, 300B, or other classic tube platforms, each amplifier maintains its own distinct musical character while still carrying the unmistakable Air Tight refinement and coherence.

Air Tight Product Range

The Air Tight range available through HeyNow Hi-Fi includes integrated amplifiers, stereo power amplifiers, mono amplifiers, phono stages, preamplifiers, and reference-level valve electronics designed for serious analogue and high-end music systems.

Products throughout the range maintain a strong focus on handcrafted Japanese construction, premium transformer implementation, and preserving the emotional communication within music rather than simply pursuing technical measurement performance.

At HeyNow Hi-Fi, Geoff and his experienced analogue and valve-audio setup team provide assistance with tube amplifier matching, speaker pairing, analogue integration, and complete system optimisation to ensure Air Tight products perform at their extraordinary full potential within each customer’s listening environment.
