The story of our two heroes

Introducing: The high-quality converter and the amplifier of the HDV 820 and their successful symbiosis.
Introducing: The high-quality converter and the amplifier of the HDV 820 and their successful symbiosis.
Inside, the high-quality ESS 9028PRO SABRE converter ensures that the digital source is reproduced faithfully and directly with maximum sound quality. Regardless of whether it is modern DSD files or your good old CD collection, you can expect a faithful and flawless reproduction. All common word lengths and sampling rates of a nearly infinite number of digital sources are supported: the inputs for USB, S/PDIF coaxial and optical are arranged side by side on the back, along with balanced and unbalanced analog inputs. Included in the delivery is an ASIO driver that supports DSD profiles on the PC. This allows you to stream content up to DSD256 at 12.3 MHz on a Mac or Windows computer, as well as PCM files with up to 32 bits and 384 kHz sampling rate. The incredible power of the HDV 820 amplifier is only surpassed by its absolutely pure and detailed reproduction. The amplifier offers a dynamic range of over 115 dB at 600 ohms, allowing for the clear identification of every single instrument. This is the crucial characteristic of an audiophile headphone, which turns the listening experience into a concert for all senses. The total harmonic distortion is < 0.001 percent, and the frequency response extends over the range from 10 to 100,000 Hz, ensuring that a faithful transmission reaches the headphones.
