Slappy:
A power line conditioner will not protect anything; a surge protector is designed to that. However, in most cases both will cause performance problems. The greater the systems resolution, the greater the potential for apparent signal degradation. What they really do is limit performance. The power supply of the amp will absorb spikes like sponge, so there is no need for one there. If you are worried about lighting; the best protection is to pull the plug out of the outlet during a storm.
