Cliffpatte,
Why not give HI-Fi news a call, I am sure they would bend over backwards and pay a fortune for someone who can judge a product in any system in any enviroment and locate what is doing what part of the performance, you sound like you could be the first HI-Fi reviewer surgeon, able to disect and locate every detail of system performance and cut out the offensive offal just by sitting in the same room.
Seriously though , how can you tell what part of the equipment you found offensive ?
I go to Hi-Fi shows when I can, and have came to the conclusion you can only judge basic system parimeters, and give yourself an idea of what may be worth trying.
I dont look for the best sounding room, I'm there to see if there are any small things that get me thinking of performance elsewhere.
I don't think I know all, but find it easy to judge what I like,
At the last HI-Fi show I attended, it was quite easy to hear Tact was not as described in the magazines, and that the Krell/Sonus faber home cinema multi channel was not as impressive as the Krell/Sonus faber strereo set up with the same movie clip.
The nordost room was very poorly set up, just by walking around you could hear this, no wonder so many think of it as forward sounding.
The Audiovalve stuff and Living voice I enjoyed also.
And the Leema had the most impressive sounding bass and an attractive girl.
I would not be able to point out one part of the above system items and blame it for the performance, it seemed obvious that room interaction, new systems , different music and the general bustle at the show make that sort of judgement laughable.
