Nordost Blue Heaven on my Sony surround receiver. I was able to try it for free. I came back a week later and gave the store the money. It transformed my system which I used for music and video. I still own those cables. Blue Heaven is 16 gauge so I would recommend the Red Dawn for it now. I use a Puritan Classic Plus on my Marantz surround processor and a Straightwire Pro Thunder on my NAD M 25- 7 channel amp. I have a separate 2 ch setup that has nice power cables. Probably the first cable you should upgrade even before you start auditioning speaker cables.
What was the first power cable that you noticed a difference in the sound?
I have bought six or seven different power cords, none over $500 and have noticed little or no change in the sound of my system. All the cables are 12 gauge or bigger. Without talking about cables made with unobtainium, where did you start hear a difference.
Thanks.
