With Sennheiser’s HDVD 800, sound is perfect. The HDVD 800 is able to connect with digital sources and is equipped with a high-quality Burr-Brown digital/analog converter (DAC) that converts digital audio data into analog signals with a resolution of 24 bits and a sampling rate of up to 192 kHz. This enables the HDVD 800 to transmit the entire frequency spectrum of high-end audio sources without any loss of frequencies.
In addition to the symmetrical inputs, the HDVD 800 also has an asymmetrical input socket; incoming signals are symmetrized before further processing takes place. Digital sources can be connected to the rear of the unit via an XLR (AES/EBU) input, optical and coaxial (S/PDIF) digital inputs or USB. All digital inputs accept signals up to 24 bit at 192 KHz*. Designed and manufactured in Germany, this high-end, solid-state amplifier harmonize perfectly and deliver an ultimate acoustic performance when paired with any of Sennheiser’s audiophile headphones.

What is a DAC?
Every digital device with an analog output has a Digital to Analog Converter of some kind. In the case of phones, televisions, and computers, they are usually stuck on as an afterthought, or just to do the job of creating analog sound to be amplified and played through speakers.
Having a standalone DAC is a worthwhile investment in any modern Hi-Fi system, essentially all the circuitry involved in creating that signal you can hear from the 1's and 0's is housed in its own box, with usually a much better design than what you would find in your television or computer.
A DAC can be useful to connect digital devices to an analog amplifier if the amplifier doesn't have digital inputs. Or if you are after a cleaner, more refined sound.
Things to listen for in higher quality DAC's are separation of sounds (how well you can hear a single voice or instrument in the mix of all the others), "textures" of sounds (raspyness of a bow being drawn across the strings of a double bass), or the clarity of echo's and quiet noises among loud instruments.
