Remember that a real life return path for current is not an ocean of zero impedance. Some engineers draw every ground as a wire because even copper planes have impendance. This approach might be one reason that makes some audio engineers more think of using single-point grounding. By discarding ground planes in favor of thin traces that wind back to a single-point ground, some audio engineers get slightly better distortion measurements, but at the expense of poor immunity to RF. The problem is that every audio circuit must work at 2 GHz — not to pass any signal but to reject noise from cell-phone radiation. Remember that every one of those long, spindly “ground” wires is an antenna. For RF noise immunity performance ground planes and connectors tightly connected to equipment metal case are good things.

Thank you for your feedback.
By the way your web page a link advertises Cell Phone Protector stickers which feel like a lot like SCAM.

Because make no mistake, these stickers are a certified scam. Back in 2002, the U.S. Federal Trade Commission (FTC) charged two manufacturers of purported cell phone radiation protection patches with making false claims [source: FTC]. In June 2011, the agency issued an alert stating that so-called radiation shields are utterly without scientific merit [source: FTC].
