I understand your post but I completely disagree. What we count on from honest reviewers is to report their findings honestly.
I DO NOT trust anyone's memory of how a $25,000 dac sounded last year at a show to a $2,500 dac recently experienced in their system. If, however, the reviewer prefers the sound of a $2,500 dac to a $25,000 dac and BOTH were compared side by side over a period of time in the exact same system, that is EXACTLY what we are all looking for.
If I ever found out that a reviewer chose to withhold that opinion because he/she was afraid they might affect someone's sales then that reviewer would be scratched off my credibility list. YMMV
