Audio Research Ref 6 power cord

Sain line power cable it's what Audioresearch uses the voice their equipment with.
I own the 6 and I also use sain line pure current p.c with great results

 Shunyata and Sain are the two favorites of ARC. ARC used Shunyata in their showroom and may still. I tried both Nordost’s Heimdall 2 and a Kubala Sosna power cord on my Ref 5se. I thought Shunyata power cords made much more of an impact. The Shunyata did not change the sound but reinforced it. Emphasized all the wonderful qualities of the Ref 5se. I have Shunyata Zitron Alpha HC power cords on all my gear and a Triton power conditioner.

Count me with the Sain Line fans.  I do also use the Synergistic Red fuses in my ARC ref6/ref75se combo, but the Sain Line cords are a more noticeable improvement.  I did not really get a boost from the fuses, but YMMV.  I have tried some other cables, but the Sain cables don't really change the frequency balance like some others, they just reinforce the natural ARC sound.

Tried a Synergistc Research Black Quantum fuse in the Ref 6. Not a subtle, but quite a significant difference, especially in the high frequencies. Less wooden, more crystalline, especially with piano. For the cost, I highly suggest anyone try one.

Im using the Shunyata King Cobra CX with a Synergistc Blue Quantam fuse in my Ref 6...
