UHF has the best overall concept IMHO. They use the same reference system and only replace one component (the one they're reviewing). Every review is done by the same trio of reviewers and they use both measurements and honest feedback.
The knock I have against UHF and a big reason why I dropped my subscription was their inability to review mainstream products that weren't SimAudio, Linn and Totem. I remember one year they must have reviewed 5 products from Copland while everybody else in the industry was reviewing 'hot' pieces from Anthony Gallo and Naim. I quickly grew tired of the same manufactures getting the reviews...SimAudio, Linn, Copland, SimAudio, Copland, Linn... it was a vicious cycle. I do believe however they use the best approach to reviewing a product.
