The DA-300USB DAC boasts the same high definition Advanced AL32 signal processing and ultra-high precision 32 bit, 192 kHz digital to analogue conversion technologies that delivers the astounding sound quality of Denon’s top of the range CD / SACD players.
Simply connecting the minimalist styled DAC via USB-B provides incredible quality computer-audio – with headphones or powered speakers – for computer stored music files or streaming audio over the internet. Alternatively, the DA-300USB is a major hi-fi upgrade; enabling audiophile playback of computer music libraries and streaming audio (from any PC or Mac) via your hi-fi, at the same time dramatically improving the sound quality of other digital audio devices, like media players, CD and DVD players, TV’s and set top boxes, Apple TV, and games consoles, by connecting them to the additional coaxial and optical digital inputs.
The DA-300USB features universal digital file format support for PCM and DSD (the native file format for SACD) digital audio signals on the USB-B input, for bit-transparent, asynchronous playback of digital music files and streaming audio from connected PCs, and PCM signals, up to 24 bit, 192 kHz, via the SPDIF and optical digital inputs. Denon Advanced AL32 Processing and High-Precision 32 bit, 192 kHz digital to analogue conversion feeds the line level outputs for connection to a hi-fi amplifier or desktop speaker system and an integrated headphone amplifier that drives all types of headphones and in-ears, for exceptional listening quality.

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.
