Replacing generic RECEPTACLES

tatooedtrackman,
Yes, I have tried first Hospital grade, then Telsa Plex, but the greatest and significant improvement is with Furutech, but not cheap.  The Furutech Wall Plate is also your futur
upgrade, but not cheap, but it works very well.  Enjoy music.

How important is the wall covers and wall frame ?????
The wall cover I think is less important, than the wall plate, because the wall plate isolate vibrations and RFI.  I tried the wall plate on GTX Gold and now, it has gave me as good improvement as a NCF Duplex alone. Enjoy music

Pay attention to to little screws, with the « Furutech Wall Plate », use only a little watchmaker's screwdrivwer and slightly thighting in an easy manner. Remember that your audio system is fed with electricity, and we (audiophile) have to pay attention to AC, AC Cable, IC, « Binding Post », all place where electricity pass through.  Enjoy music

Imagine the improvement with the carbon fiber wall cover too.

First I only had install the carbon fiber on the GTX G, nothing special noticed.  Only months later, I installed the Wall Plate, and I had noticed improvement with the wall plate. May be the fiber cover help with this favorable combination...
