I have both GTX-R and GTX-R NCF side by side. The first is fully broken in, the second is brand new but has been previously installed in the shop and an air fan worked full speed trough it for about 60 hours.
Now installed in the music room, I did not hear or feel any significant difference between it and the non-NCF (not yet). Nor did I feel or hear any of the agressive rendering coming usualy with new, unbroken sophisticated cable or outlet. An Audience Adept Response aR2p-TO is plugged into it and the amp into the conditioner. All the other components are plugged into a Chang Lightspeed which is itself plugged into the aR2p-TO.
If you want to know, the amp, a Classé Delta 2300, works much better through the aR2p-TO than directly in the wall, and the whole thing also sounds better when the Chang goes through the aR2p-TO than directly in the wall receptacle.
