Power Cord for DAC

use anything that's OCC single Crystal like zenwave, Harmonic technology, acoustic Zen and Neotech and rectangular OCC is the best for power cords not cheap though.

My experiences has shown that D.U.C.C Wire used in a Cable from a Company such as Acrolink Leggenda can offer a influence toward the description of a Sonic Signature  you have pointed toward.  

This Cable is supplied either with Plug Connectors or without, it is offered with different configurations for the Wire and Sheathing at different pricing per metre length.

Using the method where there is not a home trial period offered, and buying it as a Cable Only, and using recommended Plug Connectors will allow for a very high quality Cable to be produced at a reasonable outlay.  

Audio Sensibility is excellent and a good value.
Zen Wave Audio also excellent.

The list goes on and on and on be it a large player or small. 

Imagine how much music you could buy with $996 by spending $4 on a power cord that will sound the same as one costing $1000. This is all you need, objectively speaking.

If you like timbre and tone, Shunyata power cables are amazing. Try Alpha NR v2, and don’t feed the trolls as always.
