I'm wondering if several discs were dubbed at once, and that 
vibrations (?) from another dubbing system

A long shot perhaps, but do you have any hum/rumble and  
harmonics of those in your playback system?

In addition to the fundamental hum, its harmonics will create
a pseudo reverb effect and other distortions.  The pseudo 
reverb, however, will not behave like the pre-echo that you
are describing.  It can indeed sound like an overdriven stylus
or electronics.

A good hum removal plug-in can work wonders in this scenario.
