John Grandberg is the best. I read his reviews with great interest and appreciation. Not only does he write well, hear well and think well, but he often comes into the review with a novel approach or idea that makes it more than the usual "beauty contest" recitation that many audio reviews are.
IMO John Grandberg and Herb Reichert (Stereophile) are the best audio reviewers working today. I met Herb at an audio show and talked to him a bit (fascinating person). Would love to meet John.
