It's an audiophile webzine dedicated to equipment and music reviews. They are knowledgable and comprehensive, and will review both ultra high end as well as less expensive stuff. Generally tend to be positive in their reviews; if they don't like something, they will be more muted. The best thing to do is to go to the site and look for yourself. Not sure how they select items to review - maybe Mike can chime in on whether he's been contacted?
