Sennheiser HDV 820 Headphone Amplifier
The higher the tech, the higher the emotion. The heart of the new HDV 820 is a formidable ESS SABRE32 DAC (digital-to-analog converter) that surpasses the previous generation with an even higher resolution of 32 bits and a sampling rate of up to 384 kHz. The amplifier is also capable of playing DSD256 files of up to 12.3 MHz.
Fittingly for an audio component that delivers such an incredibly pure sonic experience, the HDV 820 has also been created to delight visually. It features a new anodized black finish with white LED lights that has been designed to perfectly complement the latest version of their flagship high-end headphone, the HD 800 S – by the way, an ideal partnership for the ultimate audiophile listening experience.
With a breadth of audio outputs that include XLR3, XLR4, 6.3 mm- and a 4.4 mm Pentaconn socket, it is easy to find the optimal way to connect your headphones with the HDV 820. It performs brilliantly with digital sources, whether optically, coaxially, or via USB, and features balanced (XLR) and unbalanced (RCA) analogue inputs.
