You are mixing 2 concepts here. $10 speakers cnnot reproduce the gamut
of signal responses. You simply wont hear certain signals no matter what
the psychoahcoustic model produces.

The german tests are probably corect. They are listening on good gear
and and tell when certain signals are missing. They can hear singlas
that are missing in lossy as opposed to nonlossy because thier hearing
range is smaller, or a subset of ours, and are more intune with what
they actually do hear.

Put those people infront of the bad speakers, and they wont be able to
tell the difference now because some of the signals that are present in
teh nonlossy format and absent in heh lossy wont be reproduced either
way.
