Power cord recommendation for a dac?

Synergistic Research Master Coupler. Synergistic is known for just the sound you described, and the Master Coupler is The Gold Standard of power cords, made for 25 years because yes, it is that good. Most of their newer/more expensive ones are even better of course, but why when you can probably find a Master Coupler used for around $250?

Any generic PC will work just fine.
Go to a hardware store....
Go to the electrical supply section....
Reach up to or into the nearest PC shelf....
Select the one of the length you need and buy it.
Anything else is a total waste of money.

Wywires Silver Juice II Digital PC. I also use Nordost Vishnu for digital and very open PC which I find has no glare whatsoever. Both great cables but different from each other. Kimber PK14 Gold would be another to read up on.

Any thing by triode wire labs.
