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 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.

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.

The Parasound Zdac v.2 is an incredibly versatile piece of kit that also happens to sound quite amazing for the price. It is a high performance DAC as well as a quality headphone amplifier and can also act as a preamp for digital sources. All for a very affordable price. What’s not to like?

Head Box S2 Digital comes fully equipped for the highest demands of the modern audiophile. It supports playback for PCM files up to 32bit / 768kHz and DSD decoding up to quad DSD (DSD256). Head Box S2 Digital also comes with five digital filters for soundshaping to the listeners preferences.

Through the worldwide success of the 866, Boulder has expanded the 800 series with the 812 DAC, Preamplifier, headphone amp.
