Power cord recommendation for a dac?

Multiple votes for Triode Wire Labs. Thanks. I'll check them out.

I would give Mark Tunis a consideration. I have his power cord on my Metrum Onyx and love it. It's also on my PS Audio amp and will be on my Auralic preamp next week. 

On a side note:  I recently purchased a 40$ Ethernet cable from Swedish Jenving (Supra). I bought it just for fun and was expecting snake oil. Much to my surprise the difference was very audible from the first second. Much clearer and a bit louder. 

Audience PowerChord. I have used the “e” version with excellent results on two different DACs. Available used in you price range. 

Supra is very good for the money. I have their power cord which I didn’t care for their ends as they feel very cheap so off they went. The Supra PC to my ears a little soft or not as open and revealing as my Wywires and Nordost. I also purchased the Supra Power Block and again very good for the money, although not up to my PS Audio P5. Lastly I use a Supra Ethernet cable to my Bluesound Vault 2 which I prefer over the cable that came with it. Haven’t tried other Ethernet cables but very happy with the Supra.
