Entreq grounding boxes

[PhilP]

Almost 20 years ago we did a few experiments to see if we could evaluate why LPs sounded so good despite having poor noise and distortion performance.
Back then producing a good transfer function of the distortion products to add was more than processors could cope with but we did some experiments with added noise, general and music related and crosstalk.
The added noise, particularly if music related, subjectively gave more air and a bigger sound stage. I wonder if these Entreq boxes add a bit of music related noise to the system?
They are certainly not grounded, and a box with who knows what inside will almost certainly be an aerial to any pickup from adjacent speaker wires, interconnects and power supplies.
This is the only explanation which I can think of which matches the "evidence" such as it is.

It's certainly an interesting and very plausible theory. The positive effects of the Entreq grounding boxes are fairly widely reported even by some acknowledged sceptics. If only someone would open Pandora's box, I mean an Entreq box, then we might have a better idea of what's really going on.
