C7 plug on Cable box or HT receiver

Has anybody replaced their stock power cord that takes the C7 ( figure 8 ) plug on their Comcast cable box or their HT receiver?

I just did . here is my take.

This is the power cord mainly associated with Comcast Cable box or some Home-theatre integrated amps, in my case the Panasonic SA-XR700. Both these units have that figure 8 type plug (C7). I always thought ,why the heck do they make a plug like this? Why not just a regular plug like everything else. How am I suppose to upgrade this goofy thing? Well, find a cable maker who already has a great reputation and ask. I found Pete of Triode Wire Labs fame. He made me up a pair of 5 foot C7 power cords,one being a 12 AWG the other a 14 AWG.
I was lucky enough to pick up a Pioneer 60" Plasma a few weeks before Pioneer decided to stop making these glorious picture TV's so my picture quality has always been outstanding. The C7 14 gauge power cord attached to my Comcast cable box just maximized my picture quality to a vivid, cleaner, deeper colors event. The picture is so dimensional now without using any 3D glasses
The pleasant surprise also that came with the gorgeous picture was the sound now coming out of the TV. I realize it is not a stereo system but the sound from the speaker bar at the bottom of the TV was always lacking in separation and detail. It was now shining through albeit to a lesser degree from the main stereo rig but at least now the annunciation of somebody speaking was clearly evident.
Onto the Panasonic SA-XR700 with the C7 12 gauge Triode Wire power cord. As nice as this digital amp is, the stock power cord should be replaced. In every aspect of the audio spectrum, the Triode C7 excelled compared to the stock cord the Panny came with. Every parameter you can mention or think of has been improved. I should probably give some credit to the Vapor Audio Cirrus speakers that this C7 power cord was feeding the power into but make no mistake about the significance that this cord produced compared to the stock PC provided by Panasonic.
I know Pete from Triode Wire is running an introductory price of $199 for these C7 power cords. Do yourself a favor and pick up one. It might be the best $199 you ever spent for either your picture quality or for your Home theatre Processor if it uses a C7 plug.
No affiliation with Triode Wires Labs.
Pangea also makes a C7 plug aftermarket cord.
You can also just buy an adapter and use any after market cord.
Thanks Morningstaraudio for the lead on another C7 power cord. I've read about Triode Wire Labs Power Cords and how they are really solid performers. I'll add this to my growing list of aftermarket power cords to try.

Ozzy. What C7 adapter have you used? The reason I ask is that the IEC C14 3 prong plug to C7 2 prong receptacle adapters I've used are a bit long. When I plug my 3 prong aftermarket power cables into the adapter after some time I see the whole think start sagging. I have a Cambridge Audio S30 CDP and was using a C7 adapter along with Belden 83803 power cords with Sonarquest ends. I had to put something underneath the adapter and power cord end to prop it up.

Thanks in advance.
Jedinite24 , I have bought them from Voodoo Cables and from Audio Advisor.
Yep, I have one on my satellite receiver. It's a PS Audio. Makes a positive difference in dynamics and clarity.
I own the Pagea Elizabeth mentions and currently use the adapter Ozzy mentions and a MAC P/C with my phono stage.
I use the PS Audio AC12 with the adapter and the Pangea HDMI off the Direct TV rcvr. Better clarity in sound and video vs. the stock cords.
