The Headonia 300B: New standards in amplification
A decade has passed since the groundbreaking design of the first Headonia 2A3, and four years since its production was discontinued. Now we are proud to introduce the Headonia 300B – an amplifier that not only surpasses its predecessors but also sets new standards in reference amplification.
In a world where headphones demand more power than ever, compromises were not an option. We designed the Headonia 300B to offer unprecedented flexibility and support headphones with different impedances and power requirements without compromising sound quality.
The power supply as the heart
The heart of the Headonia 300B is a power supply with 1000 times lower residual ripple than conventional power supplies. Complemented by amorphous double-C-core output transformers, carefully tuned input and output impedances ensure optimal performance.
Impedance matching for optimal sound
Tube amplifiers without impedance selectors on the secondary sides of the output transformers cannot match the performance of the Headonia 300B. Mismatched impedance significantly affects the tube's operating point, leading to a deterioration in sound quality. With the Headonia 300B, this issue is completely resolved. Whether you use headphones with 32 or 600 ohms, our amplifier ensures the entire sound spectrum of the music source is faithfully reproduced.
In contrast, amplifiers without impedance matching often experience distortion at high or low frequencies, negatively affecting the overall sound image. Unlike tube amplifiers without an impedance selector switch, the Headonia 300B provides perfect impedance matching, guaranteeing authentic, distortion-free sound reproduction across the entire frequency spectrum.
Solid Chassis
The design of the Headonia 300B reflects our commitment to excellence. The chassis, made from 8-10 mm thick milled aluminum, minimizes interference, while the rubber-plastic-metal sandwich feet eliminate vibrations and ensure pure sound reproduction.
Only the Best
In collaboration with leading industry companies, we have integrated components of the highest caliber. Japanese Alps potentiometers, known for their precision, and Mundorf capacitors made in Germany ensure uncompromising performance. Lundahl transformers on the balanced inputs further enhance sound quality, delivering an impressive listening experience.
Equipped with a large OLED graphic display, the Headonia 300B offers intuitive control and customization options. From adjusting the brightness to monitoring the tube lifespan, the user can perfectly tailor their listening experience.
When you open the menu, you can set and monitor the following parameters:
- Lighting to adjust the brightness to the desired ambiance
- Life Trimmer that displays the total operating time of the amplifier in hours and minutes
- Tube timer where you can see the lamp lifespan and reset the timer when you replace the lamps
- Pre-Out Option
Pre-Out
The Pre Out function expands the versatility of the Headonia 300B and allows seamless integration into various setups. With output transformers optimized for Pre Out, this amplifier can compete with devices far beyond its price range and holds a proud place in any high-end audio system.
Our dedication to user comfort also extends to the remote control. The ergonomically designed remote, made from CNC-machined aluminum, features a USB-C rechargeable battery for hassle-free charging and ensures uninterrupted control conveniently from your chair.
In a market saturated with options, the Headonia 300B stands out as a true masterpiece that redefines the possibilities of amplifier technology. Experience the pinnacle of audio engineering with the Headonia 300B – an amplifier that exceeds all expectations.
