There were some moments where things got "Twilight Zone" strange, but they did not last
The improvement I was most intrigued by was the perception of three dimensional space, which has improved to the point where reverberations, apparently from overhead is making the perception of being in the concert hall that much more realistic.
Dynamics, clarity and details are improved over the 14 gauge Neotech wire and with the improved imaging and focus adds to the perceived reality.
But I do find the amount of bass did not change from the 2 x 18 gauge solid copper from VH Audio. However, the amount of texture within low frequencies on certain tracks has improved considerably, which made the bass sound a little "lighter", but more enjoyable
I am/will monitor the brightness of the copper wire inside the PVC tubing. I am hoping that sealing each end of the tube will prove to be an effective deterrent to the oxidizing process.
Hopefully by the time the bare copper has oxidized, an alternative to Teflon Insulation will be available - perhaps foamed Teflon ???
On the positive side - the move by cable companies to the more advanced insulation types is trickling down to the parts providers, so there is a real possibility of foamed Teflon becoming more of a standard in the near future.
With that - I will sign off :-)
