Has anyone used one of the BSG Completion stage with speakers or headphone?

Should stir up some opinions.  the reviews are mixed though positive reviews from TAS and Stereophile made me take a second look.

LOL $4K for a phase maniuplator?

Wow, okay so it's $4000 for an alleged phase manipulator that actually doesn't perform as advertised...

It's hard to believe but I would not r/o that the gain boost is responsible for the many good reviews.  I think I hear the same thing (appearance of improved sound by gain boost) when I run headphones balanced
