What happened to Audio Research G Series


Audio Research released their new G Series of products only a few years ago and they seem to be discontinued already. I believe they were replaced by the Foundation Series. Why such a short-lived product line? That seems unusual for a company that's been around for decades. Was G Series supposed to be a special edition/limited release? I think the series was the first to adopt new styling (less boxy) and came about after Audio Research was acquired by a new parent company.

I don't see them on the ARC website. Their new mono-blocks have similar styling, however. Too much competition in that price slot?
