Actually many of us do have a full understanding of break in Bo. It's not just you. Many of us also have great ears and can hear all the differences in time.
As for the grounding devices, I was speaking with Richard Vandersteen about this and he shared that if the electronics are designing their grounding properly, that the devices won't be needed as they won't add anything positive.
I now have his M5-HPA mono blocks (setting them up as I type this) and my server/DAC/analog volume control is also designed properly, so the CAD won't be in my future.
I'm using my WEL XLR interconnect with my William Tell Zero and WT Bass. Amps will be running directly into the wall on a dedicated 20amp circuit. I'm going to start off with Richard's power cords, but may upgrade to the Hurricane cords. I am using Hurricane on the Server/DAC. That goes into the Niagara/Hurricane power cord into another dedicated 15amp circuit. My router and cable box are powered by a dedicated LPS unit that goes into the Niagara. Router uses Wireworld ethernet cables (2) with a bespoke hospital grade filter before going into the server/DAC. That has an isolation unit built into it.
All of this still powers my Vandersteen Quatro CT's. Still need my buddy to come and put the 3" granite plinths under them. The plinth spreads out the vibrations and holds the speakers in place so they don't' move at all. It does make a positive difference in the sound. Richard walked me through this (I'll be adding washers to the rear to keep the rake in proper perspective as the tweeter will be 3" higher. Wow, I can't even believe where my system is at. Just blessed and I know it. Thanks all for letting me play.
