Frequently Asked Questions Should I use a Balanced or Unbalanced connection? If your amplifier has a true balanced input, we recommend you use the balanced analog output from your Wadia 581se/781i CD Player. All things being equal, properly implemented balanced (also called differential) circuitry sounds better than unbalanced circuitry. The Wadia 581se/781i CD Player is a true balanced design. It generates the inverted signal in the digital domain and all subsequent processing is done in balanc

581se/781iCDPlayer Theory of Operation Using ClockLink with an External Processor ClockLink eliminates jitter added when the clock signal is recovered from the digital data stream. In a non-ClockLink system, jitter is added when the clock signal is embedded in the data stream and transmitted to the DAC. When the clock signal is recovered from the data stream (as shown below), and used to clock the DAC output, this jitter degrades the sonic performance. Data and Clock to DAC Transport DAC Jitter

Digital Algorithms In the Wadia 581se/781i CD Player there are three user-selectable digital algorithms that can be used to optimize the sonic performance based on system matching and personal musical priorities. The three algorithms in the 581se/781i CD Player all upsample to 32x the input rate (at 24 bit/1.4112 MHz DAC sample rate), but differ in their time and frequency domain characteristics. They are: Algorithm A Digimaster v2.5. Wadia’s classic time-domain interpolation algorithm delivers
