About Rega DAC-R 32bit/192kHz Wolfson USB 5-Input Digital

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 minimized 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 audio grade 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 audio grade capacitors. There is a power supply for the control micro controller, separate from the digital & analogue audio stages. Special attention being paid to the inter IC control signals ensures the control data noise is kept to a minimum.
