I'm not talking about artifical machine signal tests. I'm talking about
sitting a human being down in a studio, with real gear, and listening to
music there.

Alot of people have home theatre setups. The idea of these setups is to
produce studio like sound. Spending thousands of dollars to produce
music that sounds like it came out of a 1980's boom box is not the
intent when you drop a couple grand on audio hardware.

In my opinion, tests must be real also, with teh caveat they should be
done with good gear, and a good listening environment. Not to do so
would be foolish and would make the test meaningless.

Rjamorim's tests dont mention the hardware, or the the environment. If I
play a codec on a transistor radio next to a construction site NO one is
goign to be able to hear the difference.
