Wyrd is a low noise linear power supply and usb regenerator with a precision crystal oscillator. It kills glitches, drop outs and other nastyness from your noisy computer USB signal before it gets to your DAC. It can reduce USB signal noise from your source by up to 200,000x.
I used this between my computer and Schitt Yggdrasil until I upgraded to USB gen 5 board in the DAC, but it will work with any USB signal.
Purchased direct from Schiit in April 2017.
