I've been researching a couple of days and can't find a resource for comprehensive reviews, the best I've found is Talkbass, and not many at that. Done Google, etc and all I get back is Sweetwater, Musicians Friend and so on. Looked for magazines and found Mix, not much there either. Lots of IEM earbud reviews, especially at Head-fi.org, but very little anywhere on system reviews by non-owners. Any sources I'm missing?
