The HDV 820 is a good all-in-one DAC/Amp solution. Designed for the HD 800 series, but works very well with the venerable HD 600 series and other high-impedance headphones. The HDV820 features balanced and single-ended headphone jacks, a bevy of digital inputs, and line-level analog inputs and outputs to connect into almost any system.
There are two things that mark a quest for perfection: It is never completed, and it has the potential to bring out the most extraordinary things with the power to shape the future within its field. Enter the HDV 820, which will surely change the way you listen to and experience your music. That is, if you are lucky enough to possess headphones capable of turning the extremely high-quality audio signal delivered by the HDV 820 into an aural quality just as supreme.
When you have engineered audio components that represent the state of the art, going one better is the most rewarding task we at Sennheiser can think of. It was the task we set out on when we designed the HDV 820. Pioneering into new technological territory, we found still more sonic truth to bring to our most demanding clientele.
Virtually everything. That is what the HDV 820 will give to your headphones. So, it will be up to them to make it heard. The different timbres of two otherwise identical instruments. The distance between the musicians of an orchestra, the tension before a singer delivers the first note. It is all there, for you to discover.
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 our 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. The HDV 820 also comes supplied with a dedicated, country-specific power cable.
