Not getting five stars/globes but 'only' four is probably often enough for folks to completely dismiss a perfectly good product, so there you have your damnation.
This is would be the worst part. Why settle for 4 stars when there are 5 star products?
Then we have people joining the forums asking why their combination of 5 star products sounds carp.
Then the confusion when one publication rates a product highly but WHF doesn't, or vice versa. Then the screaming of their soul as they realize they have to spend time looking for products they like the sound of and that there is no god giving ultimate rankings of which products are best. The plaintive wails as people post threads about how can WHF give such a high/low rating to something they love (I was shocked to see a recent headphone review give 3 stars when I was sure it was a 4-5 star product, and didn't see the same issues the reviewers did with bass performance). But none of these are solved by using a different rating system.
Like any magazine/rating system, you have to first understand the criteria, consider it in partnership with the written review, and then use it to create a list of products you want to audition (WHF themselves also encourage this approach and never claim that their ratings/reviews are a guarantee of satisfaction). The biggest failings would be to rule out products with fewer stars or ignore the advice of an experienced dealer - particularly with respect to system matching - just because you read a review/rating somewhere.
