Power cables of your choice, and why?

@sealegs I am using Supra LoRad 3x2.5 power cords for my DAC and preamp.  They provided substantial improvement over the stock power cords provided by Krell and Rowland, respectively...

Passion for Sound actually found that stock cable has better clarity than the Supra Lorad power cable by itself, unless the Supra cable is used along with its "power board."  Review the video for yourself.

I am in the process of completing my loom of Cerious Technologies Graphene Matrix power cables. I have 3 components: Jay's Audio CD2 mk3 transport, Reimyo DAP-777 DAC, and Linear Tube Audio Z10 integrated/headphone amp ( into Dan Clark Audio Stealth closed-back headphones). I was using power cords by Zavfino and Audio Sensibility. I replaced two of them with the Cerious Graphene Matrix and the difference was night and day--blacker background, more dimensional imaging, bigger sound, like someone took their foot off the music hose. I just received my 3rd (and last) CTGM power cable, which will go to the DAC. When I had only two of the CTGM cables, I moved one from the transport to the DAC, and the increase in bass was prodigious. With all 3 power cords the same, I believe my 3 components will sing in perfect harmony. And I was lucky enough to pick up a pair of Cerious Technologies Lumniscate XLR interconnects to go balanced from DAC to amp. Lumniscate is CT's top line. I am waiting for delivery of a CTGM digital SPDIF cable to go from transport to DAC, and I will be finished, except for probably replacing my 20 year-old DAC with (probably) an LTA Aero. 

@sfpeloton sure. I used Furutech power cords for probably about 1 year or so. They are good cables but they have their own sound that I grew tired off. I’d say it’s an artificial coloration of high frequencies that, to me, sticks out and doesn’t sound natural. Keep in mind that I used Furutech rhodium connectors and that probably was as much of a contributing factor if not more than the cables themselves. Overall they sound pleasant, detailed and do a  nice job of reducing the overall noise floor. 
Combined with Furutech GTX-D NCF outlets the effect is even more pronounced. 
It’s all system dependent so don’t let my comments discourage you from trying these cables. 
 

My favorite Furutech power cable is DPS-4.1 and it works equally well on digital and analog as well as amps. 
As a side note I tried Furutech DSS-4.1 speaker cables and didn’t like them. 

@audphile1 Thank you for the information. Hopefully, in my system the artificial coloration will be less prominent. Should at least be an interesting experiment. I will consider it a success if I hear clear differences.

@audphile1  Same camp with Furutech DPS-4.1 and GTX-D NCF outlets.  There is a synergy and energy with that combo.  Like breathing oxygen into the organism.  You are correct, digital and analogue benefit equally.  Fun stuff.
