I'm having trouble reconciling the fact that Roger Russell would build speakers that are a gimmick.

I guess the jury's still out. At least for me anyway.
Over the years, reading Roger's web site, and knowing his work history; along with him being
anti-snake oil, as far as cables go. He just doesn't seem like the 'gimmicky' type. You know what I mean?
Since I don't have the speaker knowledge of Gene, TLS, or WmAx; I'll go along with their expertise.
Gene, is there any chance of getting a pair for review?
