Thanks Cellcbern. Puritan devices are also on my shortlist to try.My experience has been that the inexpensive Puritan Audio Groundmaster City devices are more effective at lowering the noise floor than the Acoustic Revive RGC-24. I am using one for chassis grounding and one for signal grounding. Good way to experiment with "grounding" boxes without spending a lot. My intention was to try them as a first "flirtation" with grounding boxes and then move up to one of the more expensive ones. Still using them.
Up to now I'm using with success Acoustic Revive RPT absolute for my front gears (power strip without any electronic filtering components) which has really lower the noise floor without any loss of dynamic or speed and helping revealing numerous low-level details.
