Power cord for digital stuffs?

The power cord that came in the box.   Seriously.  The power cord that came in the box.  

Seriously... Yes, I have always been using that!!

I have played around with several different power cables for digital gear. The best I have found is the WyWires Silver Juice II for this application.

I would strongly encourage you to try some alternative PC's for your digital.  Every single piece of digital gear I have run in the last 10 years has been elevated in important ways by a good after market PC (EAR Acute, BADA DAC II, Audio Note 4.1, Lampizator Big 7, Lampizator Golden Gate).  The better the DAC it seems, the more I hear this phenomenon.

Of course, it is best if you can try before your buy!

If you want to experience a different type of power cord
