I enjoy Stereophile, TAS and HiFi News and Record Review. I do not find Harley, Valin, Fremer, Reichert, Kessler or other prominent reviewers in any way dishonest. I do not believe that the magazines provide great reviews for ad money (although I know of one reviewer who will remain nameless and is no longer in the business who would provide a great review, unbeknownst to the higher ups at the magazine, in exchange for keeping the item reviewed at no cost to him--which he would later sell).
It is obvious that a brand with consistently great reviews will advertise in the magazine as their advertisements will reach their target audience and influence purchasing decisions.
One has to know the type of sound that each reviewer prefers and judge their reviews accordingly. Furthermore, a reviewer will rarely report that a component sounds terrible, but you can usually learn the character, strengths and weaknesses of each item reviewed even if the weaknesses are not set forth in bright lights. I've come to appreciate Fremer the most as he is not afraid to be more direct than most about the character of the sound of an item and precisely what he liked and disliked about it.
