Sennheiser Introduced HDV 820 Headphone Amplifier



Sennheiser introduced the latest product in its audiophile range, the fully balanced headphone amplifier HDV 820, at the Tokyo Headphone Festival. The HDV 821 builds on the accomplishments of the audio specialist’s first-ever digital headphone amplifier, the acclaimed HDVD 800. The new HDV 820’s enhanced, higher resolution and ultra low distortions components open up a whole new listening experience for the most demanding audiophiles.

The HDV 820 amplifier allows for unadulterated listening enjoyment, thanks to its improved fully balanced signal processing and extremely low harmonic distortion. It provides an incredibly pure sonic experience for every audio source.

The all new digital section of the HDV 820 is powered by a high-quality ESS SABRE32 digital-to-analog converter in a completely balanced topography. The DAC offers unequalled dynamic range, ultra-low distortion and unmatched audio clarity. It preforms at a PCM resolution of 32 bits and a sampling rate of up to 384 kHz and up to 12.3 MHz in the DSD mode.

The analogue section and the power amplifier of the HDV 820 derive from the existing HDVD 800, but in a carefully improved version. Its multiple audio outputs include an unbalanced output through an XLR3/6.3mm combined NEUTRIK socket, one balanced XLR4 and two balanced 4.4mm Pentaconn sockets. Due to its diameter of 4.4mm, it is suitable for mobile and stationary applications. The unmodulated, very low contact resistance of the Pentaconn Connection leads to a distortion-free signal transmission. The HDV 820 delivers superlative performance using digital sources, whether optically, coaxially or via USB, as well as analogue sources via balanced (XLR) and unbalanced (RCA) inputs.

Designed and manufactured in Germany, the HDV 820 has been created to be a perfect companion to Sennheiser’s audiophole headphones. The amplifier delivers a particularly impressive acoustic performance when paired with Sennheiser’s acclaimed HD 800 S headphones. This harmony is reflected by a new anodized black finish with white LED lights, a design that complements the subtle elegance of the HD 800 S.
