Denon DA-300USB Details

As more and more music lovers consider their personal computer or laptop as their principal audio source, they find that the sound quality they're getting simply isn't on par with what a premium component music system can deliver.

Denon's DA-300USB combination D/A converter and headphone amplifier elevates computer-sourced digital audio tracks to purist audiophile levels, delivering superb sound quality without compromise.

Equipped with a range of advanced digital technologies, the DA-300USB connects via asynchronous USB to the computer and features the ability to decode both PCM (traditional digital audio format) and DSD (Direct Stream Digital - the advanced digital audio format of SACD).

For connection to other digital audio sources, the DA-300USB also features three digital audio inputs - two optical and one coaxial.

Featuring audiophile grade construction with highest quality component parts and circuit design, the DA-300USB delivers a level of sound quality on par with Denon's highly praised universal disc players.

Key Technologies

At the heart of the DA-300USB is the high resolution PCM1795 D/A converter, which features advanced segment 32 bit architecture along with the ability to handle up to 192kHz PCM sample rates as well as the ability to decode both 2.5Mhz and 5.6Mhz high resolution DSD files (either natively decoded or via DoP - DSD over PCM).

Via the USB-B port, the DA-300USB communicates with the PC or Mac via asynchronous data transfer mode, which ensures smooth, jitter-free digital communication, which is especially vital with very high bandwidth digital audio datastreams. For optimum compatibility with the broadest range of sampling frequencies, the DA-300USB is equipped with two master clock crystals, instead of the usual one.

For the widest dynamic range and lowest distortion, the DA-300USB features sophisticated digital signal processing, including Denon's exclusive Advanced AL32 processor that delivers vastly improved detail especially through the critical midrange band, providing noticeable improvements in clarity with low level softer sounds.

Audiophile Grade Design

Housed in a sleek casing, the DA-300USB features no less than 7 separate printed circuit boards, to ensure the highest isolation betn circuit blocks. Powered by a 15V/1A AC adapter, the DA-300USB features sophisticated DC power conversion technology with a power block that delivers separate DC voltage sources to power the various stages.

To ensure the most stable and accurate digital audio and timing data at the critical D/A converter stage, the DA-300USB also features advanced isolator chips that combine high speed CMOS technology with unique on-chip micro air-core transformers.
