When it comes to maximising system performance, grounding is the latest area for exploration. We’ve always known about supplying a clean ground for the system’s AC supply, but taking the principle within the system and embracing mechanical as well as electrical grounding can deliver startling benefits from even well-established set ups. The CAD GCs banish noise and bring life, space, and colour in its place while the carefully considered application of mechanical grounds adds presence, energy, and timing. I’d happily recommend the GCs in any situation, while the Vortex, Nimbus and Neodio Origine B1 supports require a little more understanding/experimentation. Really rigid cases will love the Vortex, while a more flexible chassis may well prefer the Origine or Nimbus, the supporting surface playing its own part. But one thing’s for certain: any one of these support solutions properly applied will deliver a seriously impressive (and cost effective) result – and yes, putting a set of grounding feet under the CAD GCs further improves things, demonstrating that CAD units deliver both an electrical AND a mechanical ground. But, even if both mechanical and electrical grounding deliver obvious benefits in isolation, it underlines that you really don’t get the Full Monty until you implement both together. That’s when you get another of those, “I never realised just how good my system already was” moments!
