The way the Lisa's voice is recorded and processed it's can cause some speakers to sound peaked, excited or resonant. The higher the volume the more likely the problem.
Be sure to double check your turntable and cartridge set up, anything wrong there (even slightly off tracking force) can make the problem worse.
Unlike Mofimadness I have not heard the reissue but would assume it's at least as good as the 4AD and I have no problem with the original.
