I think he is called Sean Parque. He used to work AV123. Last time I heard, he was trying to make a living "upgrading" various types of speakers with "better" crossovers, damping, etc.

He has a $329 power cable for sale on his website.

He's an Axiom hater, for sure.

For my own part, I met him at an Audioholics GTG in Oregon a couple years ago and tried to personally apologize for past transgressions. He totally blew me off.

I think Skiing Ninja is (another) audio snake oil boutique.
