digital Filter in CD Player ?

Thats probably it.
Certain waveforms can actually damage your speakers, so the cdrom drive
probably doesnt allow drasic slew rates like that.

Try low pass filtering them at like 22kHz. Your CD player cant produce
frequencies beyond 22kHz anyway because the DAC output is analog filtered to
remove harmonics above that.
