This 20 amp device with C-19 power cord termination helps by Primary Earth Grounding: focused star grounding for superior sonic performace. There are 8 grounding outlets. This device is typicaly 1/2 of the full Nordost system. This takes care of the grounding of one side of the electricity which does make a nice difference, but for the COMPLETE grounding effect of both sides of your electricity, you should also include a QKore device. I have a QKore 6 on sale at this time as well along with numerous signal grounding cables the have terminations of RCA, XLR (3), USB and USBa and bananana on both sides to attach the QBase to the QKore. The QBase and the QKore used together will make a stunning improvement in your system.
