Theoretically you are right but at first I felt an irrational rejection
of what you wrote. Then I went to my stereo and listened to some music
and it came to me... The tp is actually better why take into account
the other tail? Slowly I am getting sceptical about the findings I was
so excited to report. I wonder if the rca cable could have accounted
for the difference. They where equally cheap. I don't believe in cables
as long as the have the same ohmic resistance. But they are not of the
same brand or making.

Hm, yep. We knew after each trial if we where right. But we did not
quite know it when listening.
OK, how would you arrange a REAL dbt then? Somebody has to select the
source.
