Improvements over previous generation DAC include:
  • Fully linear ultra low noise power supplies
  • Re-clocking with Crystek femtosecond jitter oscillator
  • Built in HW volume control (no Volume-Clocker needed)
  • Built in high performance headphone amplifier
  • Full size XLR connectors
  • Ability to back-power the Raspberry Pi
  • Improved thermal design
  • Aluminum case available

The PecanPi Streamer is a ready to go plug and play streamer, that uses the PecanPi DAC, and will be available with the following software options:

Preorders available:
PecanPi DAC -- 224.99 -- 25% off

The linear power supplies are built into the board, see my previous post.

So the Power comes from a switching usb then gets "cleaned"?

The short answer is yes.

The DAC is powered by a 9V power supply. It takes that power supply generates all needed voltages and cleans them up using ultra-low noise linear regulators.

The DAC also generates the 5V (non linear) supply needed for the RaspberryPi through the 40 pin connector. But you can disconnect and power Pi separately if you would like.

All the performance numbers were obtained using the 9V power supply that is included with the DAC.

You are welcome to replace that 9V power supply with a linear one on your own, it uses a 2.1mm x 5.5mm connector with positive center.
