Stay grounded


A few recent experiences have reemphasized the importance of good ground connections: I started by adding an Acoustic Revive RGC-24 to my InnuOs Zenith Mk3 streamer. Furthermore I added an Akiko Audio Black Box to the ground rail of my fuse box. And lastly I added a Chinese sourced grounding box to my Draytek router via USB connection. In each instance the effect was less than subtle: like snapping a camera objective into focus. I live in a single house with a very substantial grounding rod; nevertheless it seems that connection to ground via the fuse box is less than perfect. Thinking of adding grounding boxes to the speakers next.

I had a similar experience with Nordost QKORE. The QKORE effect was subtle at best which led me to believe that perhaps my system is somewhat immune to mechanical grounding....LOL!!  

I have two dedicated circuits in my listening room properly grounded to the rod buried next to my main breaker box. I had my doubts that these so called ‘virtual’ grounding box would make any difference. I decided to try the ‘virtual’ ground box to see if they would further improve my listening experience. The RGC-24K was easy choice for it’s unique approach, first RGC-24K was installed underneath my Accuphase Integrated (manufacturer recommends installation directly below the power transformer as the device also operates as a passive EMI/RFI filter).

Listening with RGC, the overall presentation had more subtlety as I could hear more detail and separation, everything was more "natural’’ and with enhanced definition. I also noticed, the overall sound is bit darker but deeper with the RGC-24K. I believe, the increased resolution and energy I heard was the direct result of drop in S/N ratio. Didn’t think it was possible given the components in my system and dedicated circuits but RGC-24K just manage to do that!

I am expecting Entreq boxes in next couple of weeks to try them on my router and Roon server, let’s see if they further increase my listening pleasure 😊

I am anxiously waiting on a pair of Entreq Silver Minimus Infinity ground boxes. They should be here by end of March. I will be trying them on my speakers (my speakers has dedicated grounding posts), streamer and router.
