Introducing Headonia 300B: Setting New Standards in Amplification

A decade has passed since the groundbreaking design of the first Headonia 2A3, and four years since its production concluded. Now, we're proud to unveil the Headonia 300B—an amplifier that not only surpasses its predecessors but sets a new benchmark in reference amplification.

In a world where headphones demand more power than ever before, compromises were not an option. We meticulously engineered the Headonia 300B to deliver unparalleled flexibility, supporting headphones of various impedances and power requirements without sacrificing sound quality.

Features:

Tube Amplification: The Headonia 300B features a classic tube amplification design, utilizing a pair of 300B tubes in a single-ended configuration. These tubes are renowned for their rich, warm, and natural sound signature, delivering a harmonically rich audio experience that is highly sought after by audiophiles.

Impedance Matching: Unlike many tube amplifiers, the Headonia 300B includes an impedance selector switch for the output transformer secondaries. This feature allows users to match the amplifier's output impedance to the impedance of their headphones, ensuring optimal performance and sound quality across a range of headphones with different impedances.

Premium Build Quality: Crafted with meticulous attention to detail, the Headonia 300B boasts a chassis made from milled aluminum with a thickness of 8-10 mm. This sturdy construction minimizes interference and vibrations, providing a stable platform for pristine audio delivery. The amplifier also features rubber-plastic-metal sandwich legs, further reducing vibrations for a cleaner sound.

High-Quality Components: Auris Audio has integrated components of the highest caliber into the Headonia 300B. This includes Japanese Alps potentiometers known for their precision, German-made Mundorf capacitors for exceptional performance, and Lundahl transformers on balanced inputs, enhancing sound quality and delivering an immersive listening experience.

Balanced and Single-Ended Inputs: The Headonia 300B offers both balanced and single-ended inputs, providing flexibility for connecting various audio sources. The balanced inputs, equipped with Lundahl transformers, ensure optimal signal integrity and noise rejection, while the single-ended inputs offer compatibility with a wide range of devices.

Versatile Connectivity: In addition to its inputs, the Headonia 300B also features a preamp output, allowing users to connect to external power amplifiers or speakers for a complete audio system setup. The amplifier is also equipped with both 6.3mm and 4-pin XLR headphone outputs, catering to a variety of headphone connectors.

Stunning Design: Beyond its exceptional performance, the Headonia 300B exudes elegance with its sleek and timeless design. The classic tube glow emanating from the 300B tubes adds a touch of vintage charm, making it a statement piece in any audio setup.

Excellence in Tube Technology and Sound

When it comes to tube amplifiers, the absence of an impedance selector on the output transformer secondaries can significantly hinder performance compared to the meticulous engineering of the Headonia 300B. This critical feature plays a pivotal role in ensuring optimal performance and sound quality. Without proper impedance matching, the operating point of the tube is compromised, leading to a degradation in sound fidelity. This is where the Headonia 300B stands out—it eliminates this issue entirely. Whether you're using headphones with an impedance of 32 or 600 Ohms, our amplifier ensures that every nuance of the music is faithfully reproduced from the source to your ears.

In contrast, amplifiers lacking impedance-matching capabilities often introduce unwanted distortions, particularly at high or low frequencies. This distortion can muddy the sound image and detract from the overall listening experience. The Headonia 300B, on the other hand, maintains perfect impedance matching, guaranteeing an authentic and distortion-free sound reproduction across the entire frequency spectrum. This meticulous attention to detail ensures that every note, from the deepest bass to the most delicate highs, is rendered with precision and clarity.

The Headonia 300B's commitment to impeccable impedance matching is not just a technical detail—it's a cornerstone of its superior audio performance. By maintaining optimal tube operating points and eliminating distortions, this amplifier delivers a listening experience that is true to the original recording. Whether you're a discerning audiophile or a professional sound engineer, you can trust the Headonia 300B to faithfully reproduce your music with unparalleled accuracy and fidelity.

Audiophile-Grade Sound and Construction

At the core of the Headonia 300B lies our unwavering dedication to craftsmanship and excellence. The construction of this amplifier is a testament to our commitment to delivering unparalleled audio performance. Crafted from milled aluminum with a substantial thickness of 8-10 mm, the chassis is not merely a housing—it's a fortress against interference. This robust design minimizes external vibrations and electromagnetic interference, ensuring that the audio signal remains pure and undistorted. To further enhance stability and minimize vibrations, the amplifier is equipped with rubber-plastic-metal sandwich legs, providing a solid foundation for pristine audio delivery.

In our pursuit of sonic perfection, we have partnered with industry leaders to integrate components of the highest caliber into the Headonia 300B. Japanese Alps potentiometers, renowned for their precision and reliability, allow for precise control over volume and settings, ensuring an optimal listening experience. Additionally, the amplifier features German-made Mundorf capacitors, known for their exceptional performance and reliability. These capacitors play a crucial role in maintaining signal integrity and delivering a transparent and dynamic sound reproduction.

To elevate the audio experience even further, the Headonia 300B incorporates Lundahl transformers on its balanced inputs. These transformers, renowned for their quality and performance, contribute to the amplifier's exceptional sound quality. By utilizing premium components from industry leaders, Auris Audio has created an amplifier that not only meets but exceeds the expectations of audiophiles and music enthusiasts. Prepare to immerse yourself in a world of unparalleled audio excellence with the Headonia 300B.
