Sennheiser HDV 820 DAC & Headphone Amplifier (UK) - Black | 507443

The HDV 820 is Sennheiser's reference digital headphone amplifier, created to unlock the full potential of high-end headphones such as the HD 800 S and HD 820. It combines a state-of-the-art digital-to-analogue converter with a powerful, meticulously engineered amplifier in a single elegant chassis. This is the UK mains plug version.

ESS SABRE32 conversion

At the heart of the HDV 820 is an ESS SABRE32 Reference ES9018S DAC. It handles PCM signals up to 32-bit / 384 kHz as well as DSD256, extracting an exceptional level of detail from high-resolution files. Careful circuit design and a low-jitter clock keep the conversion clean and transparent.

Powerful, precise amplification

The amplifier stage delivers the voltage and current needed to drive demanding 300 and 600 Ohm headphones with authority, while its low output impedance also suits sensitive in-ear models. Balanced outputs are provided on both a 4.4 mm Pentaconn socket and a 4-pin XLR connector, alongside a classic 6.35 mm output.

Comprehensive connectivity

Digital sources can be connected via USB, optical or coaxial inputs, while balanced XLR and unbalanced RCA inputs accommodate analogue sources. The HDV 820 automatically detects the incoming signal and selects the appropriate input, making it easy to integrate into a high-end hi-fi system.

With its anodised black aluminium housing, solid controls and UK mains plug, the HDV 820 is a long-term investment for audiophiles who want a reference-grade DAC and headphone amplifier in one device.
