Precise volume control and true balanced Class A preamplifier.
Discover a new dimension of audio excellence with the Harmony HP2A, featuring precise, tuned discrete resistive ladder volume control and a true balanced Class A preamplifier. This sophisticated design gives you precise volume control, high signal integrity, and the exceptional listening experience that audiophiles dream of.
Precise volume control for noise-free settings.
The precision volume control with discrete resistors in a resistive ladder design allows for smooth, gradual control of the listening volume. Unlike conventional potentiometers, which can cause noise and irregularities, this ladder design ensures precise, noise-free adjustments that maintain signal quality at any level. The result is a clean, undistorted listening experience that lets you concentrate fully on the music.
True balanced Class A preamplifier for pure sound fidelity
The Class A preamplifier in the HP2A features a true-balanced design, meaning each channel has its own dedicated circuitry to isolate the audio signal and keep it pure. Class A amplification is widely considered the gold standard for audio quality due to its extremely low distortion and high linearity. With this preamplifier, you'll enjoy every nuance of your music with depth, detail, and lifelike dynamics.

Discover an unparalleled listening experience with the True Balanced High-Power Headphone Amplifier, carefully engineered to bring out the finest details in your music.
Designed specifically for audiophiles, this amplifier delivers high output, low distortion, and absolute precision—the ideal choice for any demanding headphone setup. With its advanced components and thoughtful design, this amplifier ensures every nuance of your music is faithfully reproduced.
True Balanced Design for superior sound fidelity.
The amplifier features a true balanced design, meaning each audio channel has dedicated positive and negative signal paths. This architecture effectively minimizes crosstalk and reduces noise and distortion, resulting in a spacious soundstage and pure audio fidelity. Whether listening through high-impedance headphones or other demanding headphones, the true balanced design ensures unsurpassed clarity and precision.
Designed with the user experience in mind
EXICON MOSFETs for unsurpassed precision and dynamics
At the heart of the amplifier are high-quality EXICON MOSFETs, four of which are used on each channel to ensure exceptional linearity and fast responsiveness.
These MOSFETs provide a smooth, musical sound with precise transients and natural dynamics. This design allows the amplifier to effortlessly handle complex musical passages, preserving every nuance for a truly immersive listening experience.
High output power and Class AB amplification.
With its high output power, the headphone amplifier can drive even the most demanding headphones, delivering deep, controlled bass, transparent mids, and sparkling highs. Class AB amplification ensures minimal distortion by keeping the transistors in their most linear range, resulting in an extremely musical and precise sound. This combination of high output power and Class A operation guarantees an exceptional listening experience full of depth and detail.
The Harmony HP2A was designed with an outstanding user experience in mind. Every design element aims to make operation simple, intuitive, and enjoyable while meeting the highest standards of audio performance. From flexible output to security features, every aspect of the HP2A is designed to enhance your listening experience.
Flexible selection of Output mode.
The HP2A offers flexible output mode selection, allowing users to easily switch between preamplifier, headphone amplifier, or both, giving them complete control over their listening environment. This flexibility makes it easy to customize the listening experience to your specific needs, whether connecting speakers or enjoying an intimate headphone session.
Design that User comfort and Protection in the foreground.
Ergonomics and user-friendliness were paramount in the development of the HP2A. The layout of the buttons and the rotary control ensures simple, safe operation without accidentally moving the device, while the well-thought-out integrated spikes on the top allow users to position the device safely and reduce the risk of damage.
In addition, a Volume limiter for a moderate output power when switched on and prevents sudden volume peaks, and sophisticated Protection systems protect against DC, overload and temperature problems.These features together ensure ease of use, security and protection, providing a seamless and worry-free user experience.
Two OLED displays for easy navigation
The user experience is further enhanced by two OLED displays that are seamlessly integrated and like a single, connected display They provide clear and concise information about the HP2A's settings. These displays make navigating through the various settings easy and effortless, ensuring users can adjust their settings with confidence.
Multiple headphone outputs for versatility.
On the front panel, the HP2A has several headphone outputs –symmetrical XLR4 and 4.4 mmconnections for those who want improved sound fidelity, as well as a single-pole 6.35 mmConnector for compatibility with a wide range of headphones. This variety ensures you have the right connector for every headphone type and offers the versatility to connect your favorite headphones without compromise.
12 V triggerInput and output for system automation
The HP2A features 12V trigger input and output connections, allowing you to seamlessly integrate it into your system. This feature allows you to effortlessly power up the entire setup with a single command, ensuring a streamlined and automated experience. The 12V trigger makes powering up your components hassle-free, making your audio experience as convenient as it is enjoyable.
Our remote control – simplified and versatile.
In addition to the front-panel controls, the HP2A supports the same remote control as the Harmony DAC. This enables seamless integration, provides convenience for users who own both devices, and minimizes the need for multiple remote controls. This thoughtful feature reduces clutter and makes managing your audio system easier and more intuitive.
Expandable input flexibility.
The Harmony HP2A is designed to adapt to your changing audio needs with expandable input flexibility. Users can customize the HP2A's input capabilities using the Harmony LExtthat have LE-LINK connected, simply expand.
There are currently two LExt models available to enhance your setup:
- LExt PHONO: Adds a dedicated phono input so you can connect a turntable and enjoy the warmth of your vinyl collection.
- LExt IN2: Expands the connection options with a balanced XLR input and an unbalanced RCA input, offering even more flexibility for different audio sources.
This modular approach ensures that the Harmony HP2A remains versatile and future-proof, tailored to the individual needs of each user.
