What gives with Sutherland Engineering?

I've tried calling thier business with the phone number provided here on A-Gon, (913-841-3355) no luck, both times was told it was an invalid phone number. Tried emailing through the link on A-Gon, no good, the email came back instantly as undeliverable. I had no luck acessing their website from the A-Gon Link, and when trying to access their site through a listed Stereophile review, I got re-directed to a Blackjack Gambling site?

Are these people even in business? Sure doesn't look like it, and if they are, they do appear to be impossible to contact. mark
