Our take on the Arcam rDac

by Dave Bar
Arcam

Turn 1s and 0s into sweet sounding music

Why buy a separate DAC? These devices are all about getting true high-fidelity sound from digital sources like computers, streaming music players, smartphones, and more. While these kinds of sources usually have their own digital-to-analog converters built in, you can expect a separate DAC to give you much better accuracy and finer detail.

Help your digital music sound more real

From CD players and game consoles to computer-based music and Internet radio, digital audio is a big part of our lives these days. And a big part of how good these audio sources sound depends on the performance of the digital-to-analog converters tucked away inside them. A high-quality DAC converts all the digital bits back into sound with a high degree of accuracy, delivering dynamic, multi-layered music with a thrilling sense of realism. All too often, though, the DACs and sound cards found in many audio components and PCs simply aren't up to the task. That's where Arcam's rDac steps in. This sleek, cast aluminum box offers a simple but elegant solution to the problem of subpar digital sound. If you've never heard your music through a first-class DAC like the Arcam, you're in for a real treat.

The rDac sports multiple inputs to handle your digital sources.

Versatile connections for your system

The rDac gives you three ways to connect your digital source components to your home audio system:

  • coaxial digital input is ideal for connecting a CD or DVD player, Logitech Squeezebox™ Touch, Sonos® ZonePlayer™ 90, or any other digital audio component with coax out, and taking advantage of the rDac's high-performance processor for better sound.
  • optical digital is ready to take on almost any HDTV, game console, set-top box, or other digital source with optical digital output, and feed a high-quality audio signal into your stereo system.
  • Type B USB jack feeds the output of your computer into the rDAC's onboard digital-to-analog converter, bypassing your computer's sound card to yield much higher quality sound with stored music files and Internet radio.

A pair of gold-plated RCA outputs lets you connect the rDAC to your home audio system's amp or receiver, or a set of amplified speakers for a high-end, compact desktop stereo.

The rDac provides a superior way to enjoy computer-based music on your home audio system.

Positively boffo musical performance from your PC

The rDac's sophisticated Wolfson processor can accept digital music files from your PC via USB — bypassing your computer's built-in sound card for a far more exciting listening experience. You'll enjoy sweet, nuanced sound previously obscured by the noisy environment inside your PC — delicate reverberations echoing in a concert hall, or the natural decay of an acoustic guitar chord. On good recordings, every instrument and vocal will stand out clearly and distinctly in its own separate space, allowing you to follow each one note-for-note.

To achieve this high level of performance, Arcam also took great care to ensure your USB music sources aren't plagued by "jitter" — errors in the timing of the data stream that adversely affect sound quality. Jitter can make music sound harsh and edgy, and smear subtle details. To reduce jitter to the vanishing point, Arcam employed special re-clocking technology from Data Conversion Systems, makers of ultra high-end products for audio professionals and audiophiles. This proprietary dCS circuitry provides a precision timing clock to drastically reduce the level of jitter from USB music sources, delivering a stunning improvement in sound quality over standard USB systems.

Features

Overview: The Arcam rDac is an external audiophile-grade DAC with state-of-the-art digital-to-analog conversion technology. The rDac offers supreme audio quality for the most demanding music lover. Housed in a slender, precision-cast case the rDac offers an ideal upgrade for conventional sources and network audio products alike. Offering coaxial, optical, and USB digital inputs - the rDac renders music with stunning accuracy.

24-Bit DAC: The Arcam rDac is equipped with a Wolfson 8741 24-bit multilevel Delta-Sigma DAC (digital-to-analog converter). The rDac will get the best audio sound out of your sources, such as your Blu-ray player, DVD player, CD player, and your Computer - which don't have an internal DAC of this reference quality, provided by the Wolfson Microelectronics world class 8741.

USB Port: The Arcam rDac is equipped with a rear-panel USB (type-B) port. Windows PCs (XP/Vista/7) and Mac (OS X) computers running music programs such as iTunes or Windows Media Player can feed the rDac via its USB input. Special re-clocking circuitry has been deployed almost eliminating the jitter (timing inaccuracies) and noise usually associated with music in a computer environment.

Note: Supported sample rates include 32, 44.1, 48, 88.2, and 96 kHz.

Asynchronous USB Technology: The Arcam rDac is equipped with dCS (Data Conversion Systems) Asynchronous USB Technology. This unique system is usually reserved for ultra high-end HiFi and professional audio applications. Asynchronous USB technology allows a precision clock to drastically reduce the level of jitter from USB music sources and delivers a massive improvement in sound quality over the standard USB 'adaptive' system. The result is audiophile-grade sound, regardless of the digital audio signal.

Digital Inputs: The Arcam rDac is equipped with a coaxial and optical digital input on its rear-panel. CD players, DVD players, Blu-ray players, and Game systems can be connected via coaxial or optical leads to receive a dramatic increase in sound.

  • Optical: Supported sample rates include 44.1 and 48 kHz.
  • Coaxial: Supported sample rates included 44.1, 48, 88.2, 96, 176, and 192 kHz.
Note: If connecting to a television set's optical output, please make sure that you are able to select PCM as the default optical out audio format from your television's Audio menu. This DAC is not compatible with multi-channel audio signals and will not work with televisions that do not output PCM.

Analog Output: The Arcam rDac is equipped with a rear-panel stereo RCA output to connect your to your stereo amplifier or HiFi receiver.

Power Requirements: The Arcam rDac includes an external 6V switching power supply (100-240V). The rDac also includes three interchangeable AC plugs (US/UK/EU).

Pretty Good

Written By jkrumm, Juneau, AK on Friday, March 08, 2013
Crutchfield Customer Review (What's this?)
 
This is my first DAC (other than a nice Cambridge Audio soundcard years ago) and I wasn't sure what to expect. I hooked my Logitech Slim Device up to the coaxial input and my CD player to the optical input. I was able to also keep each of these hooked up to my amp through analogue inputs to compare the sound. Basically, it's pretty subtle, with improved highs and midrange, and perhaps a nice tightening of the bass. I switched inputs back and forth for my wife and she thought the same effect could be achieved by turning up the volume a little. I kept it, because it's always hard to return even a slight improvement.
Pros:
Improvements are there, but subtle.
Cons:
Expensive for what you get (compared, say, to a nice amp upgrade or speaker upgrades).

Arcam rDac

Written By Jerry, Martinez, CA on Friday, July 08, 2011
Crutchfield Customer Review (What's this?)
 
After loading my 2000 CD collection to hard disk, I needed to ensure that I could get the highest quality playback from my computer. Internet research led me to the Arcam rDac. The quality of the USB connection was the deal-maker for me. The sound quality is excellent, the device is well built, and the price is a steal. The Arcam rDac fulfills all my needs and expectations.
