I've thought a bit about that, but with so many other forums and sites covering gear, I think it's best to keep this site focused on mixing, in particular.
That said, I'm not opposed to an off-topic board, for general discussions, if there's call for it.
I'd recommend trying homerecording.com, gearslutz.com, tapeop.com, thewombforum etc for gear reviews, and general recording discussions.
