The question was a valid one, as there are no such things as stupid questions, only stupid answers once in a while. You guys are going to nit pick over terms and spelling rather than discuss the company in question. These topics that get started off that way, often snowball into having normally good and intelligent people making personal attacks on each other, that have nothing to do with the original topic. That's a waste of bandwidth, not the original inquiry or enquiry if you want to spell it that way, being not genuine.
Back to the topic:
They don't make any real outlandish claims, however the link to their brochure is dead, as is the link to their dealers and the specifications link only shows size dimensions of the plugs and outlets no real technical spec's to show that their plugs are any better than standard ones. That is itself is misleading, just by not saying anything. They mention quite correctly that the stainless steel hardware is a better build, but as far as improving an audio signal by cleaning up so called "dirty power" with a connector, nope I don't see that. You'd need a power conditioner for that, in the rare, rare case that a power company is generating power with surge spikes and brown downs enough to affect audio.
