Thanks for that. It described how wires can pick up signals/noise ( not new) but suddenly that’s coming out of the speakers raising the noise floor. The how was missing. These leaps from cause to effect are unconvincing without explanation but a showman can make them appear compelling. I get John Swenson’s points about grounding and current leakage, hence wondering about internal components/internal DC power.

I also get that amps need good power. I’d assume Meridian are aware of that and would have engineered a suitable supply. 8k power supplies are pretty chunky and I’m sure the National Grid can deliver. I’d assume they supply a cable capable of delivering the current required by their own power supplies. The conclusion would be that Meridian don’t quite understand what they are doing (even with the new high bandwidth amps in the SEs, unless they’ve changed power supply or cables), in which case 8k SEs are a bit of a leap of faith?

I’m not an engineer but just after some understanding, So thanks
