PC for LUMIN X1 ! .... Shunyata? Nordost? Synergistic Research? AQ?

@questionforhifi I can relate to your power cord confusion. There are many good choices for power cords. That is good. But also a problem to navigate through all the choices. I think it comes down to the basics. Thicker gauge is good. Highest quality conductors and terminations is good. Quality insulation is good. Start with those minimum requirements. I have Shunyata Deltas and AQ Tornados. But I do have one Pangea Audio AC-9SE MkII Power Cable with Cardas Copper. It has good conductors and about one of the thickest gauges I have seen. SQ on my Raven Blackhawk Mk3.1 where I have given it a workout was just as good as my other cables at a fraction of the price. How’s your hearing? How’s your room? How’s the rest of your system? Will you hear a difference between high end cables? One could argue to start with that cable and go from there up the ladder if you want. 

I recomemd Clarus Crimson  cables.
Detailed presentation.

If you like particular brands characteristics, why not trying certain combinations with other sections in your system? The results can be very impressive. All my sources are powered by Nordost Valhallas in my systems (D1, DAC and X1) because of the life they provide to the music.. However, my amplifiers are powered by Sigma HC and Sigma V2 for their better bass control and accuracy at the top end - No more fatigue. In short, two very different brand can complements each other.

I’m all Shunyata on my main system. I use a variety on my secondary’s; nordost, PS audio, and my favorite Analysis Plus. You may want to check them out.
