Sennheiser’s HDV 820 is the next generation of its acclaimed digital
headphones amplifier, designed to complete the Sennheiser audio
experience and perfectly complement its high-end audiophile headphone
range for the ultimate acoustic performance.
The perfect partner for reference-class headphones.
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.
The mission: Better the best
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.
The sound: Making great headphones show all their class
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 technology: Only the unsurpassed
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.
The design: Giving the eyes a taste of how it sounds
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.
The compatibility: Outstanding sound will find a way
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.
