With its two 12AX7 valves, when used as a headphone amplifier, it produces the warm, soft yet precise sound that music-lovers appreciate so much. It manages the bridging as a preamplifier. Here it is an ideal addition to the SP-996 and SP-997 monos. Now there is a small, space-saving stereo unit for harmonious, open sounds.

Hugo 2 is a powerful DAC and headphone amp that builds on the ground-breaking original. Designed for both home and mobile use, Hugo 2 transforms headphones and audio systems’ sound quality with its cutting-edge proprietary DAC technology.

The HA-3 was developed for headphone lovers searching exclusively the very special music experience.

It impresses with it’s Single-Ended-Triode technology taken to its respective extremes by Ayon in all their products. Selected in-house AA45 Mesh super triodes, the perhaps most perfect and best sounding low-power triode for headphone amp design, are applied in combination with special super-permalloy wound output transformers.

At the HA-3 deliberately all useless gimmicks have been omitted. The HA-3 is designed without compromise in its circuitry as well as in its power conditioning; therefore, a separate top-class power supply was inevitable; on the one hand it guarantees extraordinary voltage and current stability and lowest hum.

The Neo 430HA is a genuine "tour de force" loaded with numerous state-of-the-art features. This fully balanced, pure analogue amplifier using a discrete transconductance circuit topology, selectable gain setting (14 or 20dB), an oversized power supply and a defeatable analogue crossfeed circuit. Rated at 667mW at 600 ohms and 8W at 50 ohms, the Neo 430HA will effortlessly drive any headphone to its full potential.

For any of these scenarios and more, the Neo 230HAD is more than capable of the task, whatever your needs may be. Based heavily on the reference 430HA headphone amp, the 230HAD features a DSD256/32-bit PCM capable Digital-to-Analog converter (DAC) that can be used with virtually any digital source such a computer, satellite TV receiver or Blu-Ray player, and offering the same fidelity as your main music system.

The HPA-1 headphone amplifier was designed ground-up to become what we believe is one of the very best sounding headphone amplifiers available today. With low feedback, wide bandwidth and a direct coupled MOSFET output stage, this musical instrument drives even the most difficult headphone loads with ease, power and grace. The HPA-1 also functions as a line-level preamplifier that sonically rivals much higher-priced competition. The measured performance is superb and the sound even better.

Marantz HD-DAC1 Mini Component DAC Headphone Amplifier supports high-impedance headphones up to 600 Ω and supports Hi-Res audio including DSD 2.3 MHz and 5.6 MHz. It features high-quality CS4298 DAC and takes sources via USB, Optical and Coaxial inputs. It offers a pair of fix and a pair of variable analogue audio out for external AV Receiver, Pre-Amplifier, Power Amplifier and Active Speaker.

To be better than the best, this was LUXMAN\'s challenge when developing the P-750u, a new flagship headphone amplifier

The P-750u is a meticulously refined evolution of LUXMAN\'s P-700u, itself a highly respected, industry standard, high-end headphone amplifier, revered by many headphone listeners. Central to the design of this headphone amplifier is LECUA (LUXMAN Electronically Controlled Ultimate Attenuator), a high fidelity computer controlled attenuator which we feel is the ideal volume adjustment system. The P-750u also features ODNF Version 4.0 (Only Distortion Negative Feedback), a proprietary LUXMAN feedback circuit integral to this perfectly balanced headphone amplifier.

Advancing our tradition of unmatched audio performance and functionality, the BHA-1 Balanced Headphone Amplifier is our solution to delivering the finest listening experience from your headphones. Functionally a miniature power amplifier, we applied the same robust design elements to the BHA-1 amplifier that we used to develop our full size amps. Six class A fully discrete operational amplifiers generate your headphone output, delivering up to 2 watts of power for more than adequate dynamic range. The BHA-1 provides a true balanced mode via balanced outputs, or you can use the single-ended outputs for more traditional headphones. The BHA-1 also has a pair of XLR outputs which allow you to use the unit as a high quality analog preamplifier.

Unison Research’s unrivalled ability with Single-Ended valve designs is well known around the world. The SH is the company’s first headphone amplifier to benefit from such extensive knowledge and ability.

The SH uses a Single-Ended Class A design with only two stages and a passive volume control. The classic refinement of the valves combines with modern technology found in the internal USB DAC to produce something truly stunning.

Encased in formed aluminum with genuine walnut veneer, the Heritage Headphone Amplifier exudes quality before plugging in your headphones. All switches, knobs, and controls are weighted and anodized aluminum for great feel and tactile response. All analog switches operate through relays for the cleanest signal while maintaining a vintage feel.

sHP-100 is a combined USB DAC & high performance headphone amplifier. The unit supports USB, Coaxial, Optical and Analog line input and has headphone output as well as analog line output.
