As you may or may not recall, Wes Philips heard the 3.1 at, I believe, the 2006 CES, loved them, and requested a review pair. Apparently, Gallo promised him a review pair. After their non-appearance, I raised some questions, and got into a, ahem, dialog with John Atkinson. After much back and forth, the story is apparently Gallo elected not to send them for review. After reading a response from Wes Philips, I intuit from that response that Gallo's reviews were so positive that he did not need another positive review since the speakers were selling so well, and did not want to risk any negative critism that may negatively effect sales.
In light of all the full-page advertising that Gallo did when these events transpired, I doubt advertising had anything to do with the non-review in Stereophile.
