Maximize the potential of your digital audio!
The Rega DAC is a 16/20/24-bit at 32kHz to 192kHz digital to analogue converter incorporating an enhanced version of the Rega designed circuit. Developed to be simple to set up and use, the Rega DAC is designed to optimise performance from any two channel PCM digital audio source such as a CD player PC or streaming device.
With the PC/Laptop and MAC now widely accepted as creditable mediums for storing and streaming music. The use of high quality lossless files such as WAV, FLAC and ALAC offer performance through the DAC equal to and in some cases better than red book CD.
Housed in a custom aluminium and steel case and boasting a pair of Wolfson DAC IC's, 5 user selectable digital filters, two isolated Co-axial inputs, two Toslink SPDIF inputs and an isolated USB input. The Rega DAC is designed and engineered to perform way above its class.
The input stage comprises a Wolfson digital receiver with a high stability low jitter clock. The receiver and PLL have their own dedicated power supplies. The DAC stage comprises of a pair of parallel-connected Wolfson WM8742 DAC's, which are driven via a buffer stage, which ensures the integrity of the data being fed to the DAC IC's similar to the arrangement used in the Isis (Rega's refrerence CD player). Great care has been taken to remove noise generated by the PC and other input sources. During development this was identified as a major drawback with many DAC's on the market today.
The output amplifier employs a discrete differential multiple feedback filter and output amplifier, with a high cut-off frequency for use with higher sample rates. We decided not to use a sample rate converter and process the data at the incoming sample rate which keeps the signal processing to a minimum. Jitter was minimised by synchronously clocking the digital data with our receiver PLL (removing any jitter from the input signal).
All the capacitors associated with the analogue signal path are Nichicon FG bypassed with MMK polyester capacitors, and low impedance conductive polymer capacitors are used for DAC decoupling. The power supply utilizes a toroidal transformer, fast rectifier diodes and again Nichicon FG capacitors. There is a power supply for the control microcontroller, separate from the digital & analogue audio stages. Special attention being paid to the inter IC control signals ensuring the control data noise is kept to a minimum.

"The Rega DAC is an excellent choice for anyone thinking about archiving vinyl, provided you have an excellent-quality analog setup with which to capture it. ... On many levels, I found the sound of the Rega DAC more akin to that of its flagship turntable the P9 (which has been a long-term component in my reference system). It shares the P9's quick and open presentation with a healthy dose of pace and timing."
- Jeff Dorgay, ToneAudio magazine, December 2010
"You'll gravitate toward the Rega DAC for its distinctively Rega sound quality: rich, full-bodied, tube-like… I can't think of any better way to upgrade while keeping, say, a Rega CD player as a transport."
Vinyl records are able to capture the purest quality of recorded music in true form. This is possible because the initial recording is captured on an analog source (usually tape) for the ultimate in High Fidelity sound, it is then pressed onto virgin vinyl. Analog recordings capture the bottom end (or bass) while adding sweetness to the high end (or treble) better than any digital recording ever could. Analog systems are still commonly used before they are digitally transferred to CD. This means that the sound then is altered in the transfer process when CD's are produced. The word fidelity means accuracy and faithfulness. High Fidelity sound is faithful to the original sound made by the artist, capturing maximum accuracy of what was intended for the listener to hear. Vinyl records capture those sounds for the ultimate High Fidelity listening experience!
180/200 GRAM Vinyl LP
These vinyl records are produced with 180 or 200 grams of high definition premium grade virgin vinyl. This is a higher quality audiophile pressing than the typical vinyl record of 100-120 grams. These limited edition LP's are manufactured with the hi-fi enthusiast in mind. A 180 or 200 gram LP is sometimes also referred to as an audiophile pressing, there is a higher bass response and an even warmer High Fidelity sound. 180 or 200 grams LP's are typically manufactured in limited amounts and are considered collectables, commanding a higher price.
Typically, a vinyl reissue is a repressing of an original LP, usually extracted from the recording's master-tapes. In some cases, reissues are remastered to lower surface noise and improve overall sonics. Reissues help preserve the music of an original recording, especially when original LPs become unavailable or can no longer be found. Reissues can be pressed on a variety of thickness from 150 gram to 200 gram and offer a great opportunity for records collectors to own many classic recordings.
