I agree that reviews are mainly for entertainment, but I certainly like them when I learn something. One of the things I like best is when reviewers do comparisons - it doesn't have to be in-depth, but the comparisons often shed the most light. Anthony Cordesman had a whole series of reviews in the old Audio that contrasted $10K speakers. Wes Phillips is good at comparing speakers in this way. Again, I'm sure there is a reluctance to do so based on not wanting to alienate and an attempt to be "fair", but the comparisons can be very useful without coming close to being inflammatory, and I wish they were done more often.
