Best power cable to use for Raysonic 168?

I used a VD David 2.0 that was very dynamic but was to forward for my current system. I tried a Purist Aqueous Anniversary and found that to be a good combo with the Ray 168, it created a bigger sound stage, fuller notes,tightened the bass, helped definition and it even changed the CD's (kidding). It brought the Ray close to my CD3 MKll, I thought that was pretty fantastic!! I also tried the Purist Musaeus it had similar attributes to AA but to a lesser degree. What tubes are you using? Are you using RCA or Bal? What are you looking for a power cord to do?

I used a Statement SC and switched to a My Audio Cables Digital.....more open sound, like removing a veil..the PS Audio is good but it smoothes things out at the expense of detail...if you try the MAC order with the Furutech F11 gold connectors....much better grip and a little better sounding that stock Marinco. BTW I hope this is the last cdp I'll ever have to buy and want it to last until the server technology matures.

Thanks for the responses! I am using balanced on my whole system. Tubes are 6h23 Russian Rocket logo from purchased at Upscale Audio.I have no complaints with my set up that can't be solved with upgrading my speakers. I am just trying to get the most out out of my current CDP and system.

Depending on how much you have to spend and what you think you want to improve I would look towards upgrading to Amperex/Mullard/Siemans tubes the Ray responds well to tube rolling and the sonic benefits would be greater than with a P/C. I run Amperex 6922 PQ US white lable( a pair of Phillips SQ miniwatt E88CC 6922) for sale @ $159 on AgoN the same as the Amperex's PQ. Food for thought.

Samhar,
I have not done much tube rolling.I did try some Sylvania 6922 as well as the stock tubes but was not impressed. Quite frankly its quite confusing with all of the tubes available, different labels, and munufacturers and such. Although it would be something I would be interested in. One question I always had with the 168 is do all 4 tubes need to be replaced? I think the inside 2 are for the balanced end. Am I correct?
