Douglas_schroeder, you say that Mrtennis is saying, "I can't really determine what this component sounds like because I used it in a system, and I have no clue what it might sound like in your system. Weight my comments accordingly."
Apart from the last part of what you say he is saying, it is a true statement in my opinion. As reviewers, we have to hope as do our readers that there is a good deal of communality between our systems, hearing, and tastes. I suspect there is but this sharing is not total. Every time I attend a show and learn what rooms are rated "best sounding" and I totally disagree, I am aware of the lack of sharing.
At its best reviewers, I think, can say this component, cable, etc. deserves your serious consideration. I have also learned over time, that from some reviewers I should ignore this recommendation.
