Horsepucky. I have *never* heard an amplifier which could be sonically
distuinguished, which did not have an *easily* measured defect.

Maybe it would help if you set your speakers up right. Then you might hear the
fact that they are under-powered. Here is a hint for set up. Right speaker goes
on right side, left speaker goes on left side. Maybe you can take it from
there. You could always check out pictures of how Mr. Bloom, the designer, usde
to set up the same speakers.
