I hear what you're saying, Gary, but this is exactly the mentality that worries me. Am I reading a bunch of watered down comments from owners, because they are too scared to voice their true opinion because they don't want to upset the builder (Alan)? Or, are those that are not overly impressed with the amp still towing the party line simply to keep their re-sale potential higher? Regardless, when I see reviews ranging from "the best" to "meh", it really makes me wonder. Add to it that I am reading the majority of these reviews on TGP and, well, you know what I mean.....
Just because someone doesn't like a given amp doesn't mean the amp is no good, for precisely the reason you highlight: one man's "grail" is another man's "fail". I don't think we should shy away from voicing our true opinions of products. It's not being unfair to the builder/manufacturer, it's just sharing a personal opinion!
