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."
