My GTX NCF has been cooking for 144 Hours and finally installed replacing the GTX.
The same familar sounds emerged when i hit play.
First impressions are that it is slightly cleaner and with a touch more clarity.
Gbmcleod's impression that there is a slightly less weight in the 100-400hz region allowing for a more revealing upper bands to emerge.
Maybe needs more burn in time compared to my well run in GTX. I certainly cannot say there is more smoothness or organic sound, even if so, a slight difference.
The GTX has a slight veiling or cloudy sound (i.e slightly more distortion and clarity).
I attribute the main improvement, not knock your socks off improvements) to an overall clearer lower mid regions allowing the rest of the spectrum to emerge.
The Black outlet which replaced a Teslaplex gives in comparision a bigger difference when swapped out. But bear in mind, it is also a different branded outlet, so the sound is subjectively not cut from the same roll of cloth. So its more comparing Apples to Oranges (though, that flavour of 2M volts) still shows.
The Black outlets has even less presence in the 100-400hz region and has zero of the GTX's richer, livelier, upfront and sparkly type of Copper/rhodium signature, which i find may excel in some systems or shine playing more towards a "audiophile recorded material".
Off this topic, having introduced a synergistic HD Ground cable . I hear the familar direction of "UEF / Quantum tunnelled" signature sound come through. I have never used any other Synergistic cables, but used a number of their tweaks.
