The Sennheiser HDV 820 combines high-resolution digital conversion with a sophisticated headphone amplification stage in a compact, premium chassis. It is designed as a reference-grade solution for critical headphone listening, making it particularly well suited to high-end Sennheiser headphones and other demanding audiophile headphones.

At the heart of the HDV 820 is an ESS 9028PRO SABRE DAC, providing detailed and precise digital-to-analogue conversion. The amplifier supports PCM audio up to 32-bit/384kHz and DSD256 files up to 12.3MHz, allowing it to handle high-resolution music collections with ease. Digital sources can be connected through USB, optical or coaxial inputs.

The HDV 820 offers extensive analogue connectivity, including balanced XLR-3 and unbalanced RCA inputs. Its headphone section includes XLR-4 balanced, 4.4mm Pentaconn balanced and 6.35mm jack outputs, providing flexibility for different headphone cable configurations. Maximum output power reaches approximately 480mW at 1kHz into a 600Ω load through the XLR-4 output.

With a frequency response of below 10Hz to above 100kHz, THD+N below 0.001%, and dynamic range above 115dB at 600Ω, the HDV 820 is engineered for exceptionally clean and transparent reproduction. Adjustable gain settings also allow users to optimise the amplifier for different headphone sensitivities and listening preferences.
