That honestly has nothing to do with what Dan said.  He never said the XBL^2 built by another vendor was inferior.  What he was saying is that all XBL^2 drivers are not equivalent, they are not the same driver.  XBL^2 is just a part of the equation, you still have to design an entire driver around it.  People have fallen under the misconception that all XBL^2 drivers are "exactly the same"....forgetting that XBL^2 doesn't determine how the entire driver design, as a whole, will behave relative to another sub.   The comment that sparked this whole thing was basically "Why would I pay $XXX for an Adire driver, when I can get the exact same thing from AA for half that."  (in reference to the MSRP pricing on Adire's webpage).   I completely, 100% agree with Dan's comments, and anyone with any common sense should have taken them as "obvious statement of facts", rather than an insult to a competitor.  I also feel that AA simply jumped on the opportunity to smear someone's name in the mud while promoting their new technology.  This wasn't the reason, it was a timely an opportunity.  Frankly, I kinda look down on AA after this.......
