Synergistic Research Euphoria HC power cord.

@bwguy I haven’t tried this cable but tried their lower end model and it was a bit too lively to the point of being bright plus it was super rigid and difficult to maneuver. It exhibited the same sonic traits on everything I tried it on…dac, preamp, amp. I sent it back. I wouldn’t be looking at Synergistic but that’s just me.
I looked at your system photos and there’s very little in terms of acoustic treatments so go easy on lively sound

Also, if you are talking to The Cable Company and thinking of buying from them, use their landing library and borrow several cables to try (you get credit towards purchase after).
I’d look at Audioquest Hurricane or Dragon, Shunyata Alpha and Sigma, Audience FrontRow.
Shunyata and Audience will be most flexible if that matters at all.

Thanks audphile1.  I have on order some acoustic panels from GIK. Hope to have them soon. Jason at the Cable Company did say they were lively, and thought Audioquest cables (I asked about the Hurricane) were dead sounding by comparison. However, everything I read about the Hurricanes is positive. The SR power cord is very pricey so I may pass on it.

I disagree with Jason. But like I said, their landing library is the way to go. The only way you’ll know if the cable is a good match is to try it in your system. I would also wait until the panels are in place before making any changes at all. 

@bwguy John (in addition to Jason) has also helped me. He’s straight forward with his recommendations. If you can get both cables in to demo you will have your answer. I’ve chosen SR over a number of other major cable brands.

Shunyata Sigma is one I am interested in also.  I have Mac amps, which is why Jason recommended Synergistic Research.
