Huh? I would think that all those things WOULD be mitigated by slowed
playback. A resonance at 30 kHz is better than one at 15 kHz (e.g.)!

The fundamental arm/stylus resonance is more like 8-12 Hz, not
15 kHz. Playing it at half speed then converting to normal would move
for example, into the 16-24 Hz region.
