@mbolek Thank You for informing me.
This one will be of real interest; I have others who were introduced to PC Triple C through me directly as a result of loaned Cables for Demonstration and also via me due to impressions made and shared from demonstrations given.
The reports are quite impressive from those who I do not know.
I or nobody else I am aware of has reverted back to a previous used Wire in a Cable.
As said one individual even cannibalized a Cable and used the PC Triple C Wire to produce Tonearm Wand Wires
As the XLR is in theory a Low Eddy Connection and the PC Triple C is a Cable that can really impress, I look very forward to the update on the Helix Thread.
When the Speaker Wire was used there was a need to burn in, which took about an hour, something happened, in that time and the A/B to the older cable in use was quite something, the Triple C superseded it without any reservation.
I am not familiar with a XLR Configuration, there might be a need to give it a Burn In Period as I had with the Speaker Cable.
