• 8 months old, bought directly from Farad • Stock configuration • Asking $300 • I accept PayPal One of the cleanest and most dynamic sound power supplies out there. Comes very close to a SR4. It has improved everything I've put in front of a Super 3. I have 4 Farads in my system powering everything digital. I've recently changed my config from ISORegen to tXUSB and don't need the 5V any more.

I have an Allo Boss DAC 1.2 installed on a Raspberry Pi 3B+ running Moode 4.3. 1) If I have J25 installed and power the DAC and Pi from a single 5V power supply, music plays, all works. On the Boss DAC, both the power LED and LED1 light up (green). 2) If I remove J25 and use two 5V DC power supplies, one to the Boss DAC USB-C and the other to the RPi3B+ USB Micro-B, it seems the DAC does not work. Only the power LED lights up, but LED1 remains dark no matter what. When I try to play a music file, I get this error: MPD errorFailed to open "ALSA default" [alsa]Failed to open ALSA device "hw0,0" Nosuch file or directory It appears the DAC is not working with J25 removed. What could be causing this?

I would like to be able to use the Boss DAC 1.2 with separate power supplies for DAC and Pi, since that is supposed to perform so much better.
