Power cord recommendation for a dac?

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. 

Triode Wire Labs Digital American or one of the new Shunyata Digitial power cords.  The 14 gauge starts a $195 with the 12 and 10 gauge higher but still in your budget range.  

+1 on TWL cables.
