I have used a number of good aftermarket power cords on my Denali and they all seem to work well, I can't say that one sounded better on the Denali than another. Examples of what I have used: Shunyata NR, Furutech DPS-4, Cerious Technologies Graphene Blue and yellow, Matrix, Elrod EPS-3 Signature.
Shunyata Denali Power Cord
Just got a Shunyata Denali 6000T and was wondering what other users are using to power the unit. I have a Delta NR on loan which sounds great but I'm wondering if the NR capabilities of the cable are redundant given the CCI filters built-in to the Denali. Curious for any advice, thanks!
