My Experience to date, is that the PC Triple C requires a burn in period, where the time period to produce the most noticeable change has been with it being used with Speakers.
The PC Triple C has from my experiences, shown change as a betterment almost immediately when used on a Digital Source and SS items, especially SS Phonostages and other SS Amplification.
PC Triple C from my experiences has a much more subtle effect for the better, when used on Valve Equipment, the effect made, once recognised (which might be related to a burn in period), is enough to assure oneself, it is worthwhile maintaining.
I am also an advocate of D.U.C.C Wire as well, when used as an Interconnect with both Pure Silver and Pure Copper RCA's. My experiences of using this Wire is one where it has been detected the Wire is capable of adding a hint of weight / richness and not being compromised in any of the attractive revealing qualities.
