Monster Power conditioners. Anyone using one?

DON'T USE ONE.

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 system’s 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.

Slappy:
Systems with low resolution will APPEAR to produce a cleaner signal with a line conditioner. Remember,” when you drain the swamp you expose the alligators”. ANY device on the supply side of the electronics must face the full wrath of the line [AC current], there is no protection from the power supply. The switching of the AC line is intense, devices like resistors, capacitors, wire etc. will resonate or ring to the tone of the 60 HZ; this creates distortion. The greater the overall resolution the more obvious this problem becomes. Surge protectors attempt to “clamp” the AC; produces even greater harmonic difficulty.
If you need greater outlet capacity then use a power strip that plugs directly into the outlet with no power cord,Woods makes a real nice one that can be "daisy chained" together.
