From the Audio Research Website:
We are pleased to introduce the new DAC8 digital to analog converter.
Although physically similar to its predecessor, the DAC8 represents new
engineering that advances the state of the art in high resolution USB audio
and S/PDIF audio.

Audio Research has maximized the USB capability of the DAC8 by incorporating
USB 2.0 HS (High Speed) which runs at 480Mbps. USB 2.0 HS has a lower jitter
specification than USB 2.0 FS (Full Speed 12mbps), consequently the DAC8 is
capable of reproducing music at higher definition/resolution (up to 24/192)
than products communicating at USB 2.0 FS speeds (24/96).

In addition, the DAC8 employs a low jitter Dual Master Oscillator design
that will provide superior digital to analog conversion via its USB 2.0 HS
input as well as via the more traditional S/PDIF (RCA, BNC, Toslink and
AES/EBU) inputs that are also included on the DAC8. Our USB 2.0 HS audio
interface is optimized for all six sample- rates currently in popular use;
44.1, 48, 88.2, 96, 176.4 and 192kHz.

In the past, S/PDIF was the default interface mode for High Resolution music
files at 176.4 and 192kHz. Now, with Audio Research's Dual Master
Oscillator, USB 2.0 HS interface, and our Quad D/A converter design, USB
audio is finally elevated to the status once dominated by S/PDIF.

Consequently, regardless of whichever digital input you select, the Audio
Research DAC8 promises to provide a superior listening experience.

In addition to the High Performance USB design, the DAC8 features:

"DAC8 HD Audio Device" software drivers, which allow listening to your music
in its native sample rate as well as assuring BIT PERFECT, low jitter, data
transfer from the computer to your DAC8. Because PC and Mac operating
systems do not adequately support sample rates over 96kHz, Audio Research
has developed ASIO drivers to make the USB audio experience sonically
transparent at all sample rates. Sample Rate measuring function: Measures
and displays the correct digital sample rate being sent to the DAC8. This
works in USB as well as S/PDIF mode. Consequently, at a glance, you always
know exactly which sample rate is being decoded. The DAC8 employs four
24-bit D/A converters. Each channel uses dual 24-bit D/A converters running
in mono mode to lower the noise floor and increase the dynamic range. Dual
Master Oscillators: When the time base of any DAC is not an integer multiple
of the digital music sample rate, decoding and quantization errors occur.
Consequently, the DAC8 uses two low jitter Master Oscillators; one for 44.1,
88.2 & 176.4kHz sample rates and the other for 48, 96 & 192 kHz sample
rates. The DAC8 automatically selects the correct Master Oscillator the
instant digital music is detected at the selected input. All inputs are
galvanically isolated from the source to reduce or eliminate noise and/or
jitter from entering the DAC8. The Analog amplifiers in the DAC8 have
received the same attention to detail as the digital section. Each channel
of the DAC8 uses a true direct-coupled differential amplifier with a
bandwidth in excess of 90kHz. The DAC8's USB and S/PDIF inputs are designed
to accept signals from an HRx, 176.4kHz, 24-bit, High-Resolution music
server system playing HRx's DVD-R recordings. See
www.referencerecordings.com/HRxSETUPS.asp for recommended music server
setups. By virtue of all of the above points and our proprietary software
drivers, intrinsic jitter has been reduced to less than 10ps.

DAC8 HD AUDIO DEVICE SOFTWARE DRIVERS:

The DAC8's USB driver software provides your computer with special
high-speed audio drivers not supplied by MS Windows or Mac OS. The Audio
Research USB drivers are specially designed to assure low jitter BIT PERFECT
data transfer between the server/computer and the DAC8 at all sample rates.
Our drivers setup the USB interface to guarantee bandwidth, independent of
active bulk transfers from the hard drive.

From the ARC icon in your computer's input tray you can set the DAC8 to any
sample rate from 44.1 to 192kHz and allow the music server/management
software to up or down convert your music to the selected sample rate.

Music lovers can use custom sample rate conversion algorithms or other file
formats provided by third party suppliers such as Windows Media Player,
iTunes, J Rivers Media Center, Media Monkey, FooBar, and many others to
optimize your music experience.

The DAC8 is a fully balanced, zero-feedback, solid-state design utilizing a
direct-coupled FET output stage with generous regulated power supplies and
seven stages of regulation. There are separate new digital and audio power
transformers, and the board material is the same as what we use in our
Reference products. Dynamic, forceful, immediate, and possessing remarkable
resolution and transparency, the DAC8 is a sonic knockout that is worthy of
the finest music systems.

With a choice of high-resolution 24/192 S/PDIF inputs (RCA, BNC, AES/EBU and
Toslink) in addition to the highest resolution 24/192 USB available, the
ability to adjust sample rates, the DAC8 provides the new standard in high
performance digital music playback.
