What was the first power cable that you noticed a difference in the sound?

I can say the days of OCC Wire are now over in my system due to my adopting the use of PC Triple C Wire.

I have been an advocate of PC Triple C Wire for a period of time and have been instrumental through loaning out Cables using this Wire. I can assure you that some very enthusiastic users of Audio Equipment have now moved to PC Triple C Wire used throughout their systems following their encounters with it in Loaned/Demonstrated Cables. 

One such encounter was with Power Cables, I loaned a PC Triple C Wire Power Cable with a Purchase Value of approx' £200 per metre, to a individual who has a lot of respect throughout the UK. The individuals system receives very good appraisal and the work they carry out on Audio Devices as work for betterment is very well known. This person has a lot of friends with Audio Interests.

The initial experience of the above individuals experiencing PC Triple C wire was with myself present. I was keen to hear it in use in a System not using Valve Amplification and the system it was to be added to is SS Amplification. 

The owner of the System, put a current through the Cable for approx' one hour before the demo' took place.

On adding the Cable to the Phonostage, the effect was immediate and to both listeners there was a more to be heard on offer and each track played was  assessed as a betterment.

Very Similar happened with the Power Amp.

It was agreed on the day that my choice of Plug and IEC for the Cables were able to be improved upon and more could be expected if this was addressed.

I left the Cable with this individual to swap out connectors and further assess.

The assessments went further than I thought would occur, a local group got involved and purchased other types of Power Cable produced using PC Triple C Wire.  

The A/B Comparisons took place with a Group present at the system I loaned the Cable to.

The out come was quite interesting, especially allowing for the follow up evaluations.

The Group were all in agreement that the Cable seen in the Link, when terminated with Solid Copper Plug/IEC had an impact on the sonic being produced, that was a betterment to the previous Power Cables in use.

I am satisfied with my contribution to the Thread, especially showing a particular Cable Type using PC Triple C Wire, that has caused quite a positive impression on more that one person.

The Wire in use as a result of my loaning Cables, has also caused one well known producer of Cables in the UK to have as the end result of experiencing PC Triple C, the use of it in a Cable supersede their own Cable designs. 

The Link I put up, clearly shows not too much monies are needed to acquire a length and have the experience for oneself.

Pure Copper Connectors will add to the cost of not already owned. 

I have been inquisitive and like to step around anything that relates to the following.  

  "There is a principle which is a bar against all information, which is proof against all arguments and which can not fail to keep a man in everlasting ignorance-that principle is contempt prior to investigation."

I have no dispute with the methods used by some to gather their info and conclude their investigations. If one chooses the route of discussions being had, or reading about PC Triple C Wire used as the Signal Path in a Cable, that is their choice.

What I do have at my end which is at least one stage further on as an investigation is the experiencing the Wire in use in my Home System, with the outcome being that I have exchanged nearly all Cables and the Wire PC Triple C is now the most common Wire in use, where it has superseded the use of OCC Copper and Silver. 

The PC Triple C Wire is not the chosen Wire for the Digital Source, after further investigations and extending this to being an experience. The Cable used has   D.U.C.C as the Signal Wire used between CDT>DAC and is the umbilical type I regularly offer as a suggestion to others.

Additionally, all Cables I am using are not assessed from my own experiences, as a social individual within HiFi, there are Demo's and Loans made of owned Cables to be used in other systems.

I have also received feedback from adopters of PC Triple C Wire within this Forum Threads, where it has been made known something was present that was an added attraction over the previously used OCC Wire.

I am yet to be confronted with anybody suggesting the use of PC Triple C in place of OCC has been a experience where some sort of betterment has not been perceived, when the PC Triple C Wire has been used for the Signal Path or Power Supply.     

As stated before, I attempt to step around adopting any attitudes shown from myself, where the forming a evaluation without a direct experience is the intention. I avoid if possible any attitude that can relate to the following:   

  "There is a principle which is a bar against all information, which is proof against all arguments and which can not fail to keep a man in everlasting ignorance-that principle is contempt prior to investigation."

"What was the first power cable that you noticed a difference in the sound?"

As stated, A Power Cable with a PC Triple C Wire.

Not much to be discovered, not sure my recollections have any thoughts worthwhile reporting on, in relation to my experiences between OFC and OCC Wire used for this purpose.

Wire Gauge differences have been known to create a difference to a sonic, but I have not worked with type of investigation, even though I am aware the link to the PC in my earlier Post in this thread has wire that is a different gauge to the Wire I have in my PC containing PC Triple C Wire.
