HDV 820 headphone amplifier
Building 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 distortion 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 topology. The DAC offers unequalled dynamic range, ultra-low distortion and unmatched audio clarity. It performs 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.
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. With the Pentaconn Connector, the Japan Electronics and Information Technology Industries Association (JEITA) has set a standard for balanced headphone connections, which will minimise today’s complexity of non-standardised connectors.
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.
“The HDV 820 builds on the accomplishments of the HDVD 800 with greater resolution and enhanced connectivity, an evolution that provides a sound experience so pure and engaging that the listener could be sitting right in front of the audio source. The HDV 820 shows what is possible when you believe that sound is not something just to be listened to, but rather something to be experienced,” explained Manuel Ricke, product manager Audiophile at Sennheiser.
