AC Power cable for ARC Ref 5 se.

 Power cords known to work well with ARC geare are Sain Line, Shunyata, and Synergestic Research. I have heard good things about Wireworld and Transparent but don't know anyone who uses them. ARC uses Sain Line and Shunyata power cords and cables in their listening rooms. They also use Shunyata VTX internally in thier Reference gear.

 I chose Shunyata Alpha HC for my ARC gear. But that was a few years ago. Sane Line was slightly better but much more expensive. I have had both ARC Litz cable and Synergistic Research in the past.

To @lostbears list I would also add AudioQuest -- my primary ARC dealer (Optimal Enhancement) always gets great results combining ARC amps with the latest AQ cables and I'd imagine the Storm series would be a great match -- I currently use AQ WEL on my Ref 2SE Phono and SR Galileo LE on my Ref 40

lostbears. How is Shunyata Research Python Helix Alpha .. Also would i need a 15 amp PC? 

Also How is  Shunyata Research Python VX  ?

 I have not tried Audioquest in years. Though I do use their HDMI and Ethernet cables in my network with great results. I have tried Nordost Heimdall 2 and Kubala Sosna, I forget the name but it was the black one. My Ancient ARC Litz cable was better than either of those. Really the Sane Line was the first cable I found that was significantly better.

I have only tried the Shunyata Black Mamba HC and Alpha HC. I don't have a Shunyata Dealer near me. I have heard that their new Delta cable is excellent, as good as my Alpha. Go with the HC (high current) version of whatever cable you choose. The ARC Ref 5se and Ref 2se use 20 amp power cords. While my Ref CD7 has the normal 15 amp power cord.
