Is someone who works for a large corporation that installs systems of this type every day the one who should be doing an objective evaluation of this subject? Visit his company web site and see if there may be some reason for bias. I work in the low voltage industry and can attest to the fact that its not what you measure on your DMM that kills your equipment. Try hooking a Power Quality Recorder on your house and get ready for a scare. Its no wonder that electronics don't last like they used to. It is not the components it's crappy power. I am not an engineer, however, I have repaired numerous pieces of equipment that have failed for unexplainable reasons. It's funny that it is always varistors, transorbs, and diodes that go bad. Odd that some of the components that are designed to shunt over-voltage and control power quality on the circuit regularly fail. I don't think this is a component issue industry wide. Daniel B House
