this article makes it sound like spikes or ripples in the AC power can cross over through toand affect the consistancy of the DC output.

"For critical electronics applications a linear regulator will be used to stabilize and adjust the voltage. This regulator will also greatly reduce the ripple and noise in the output DC current. Linear regulators often provide current limiting, protecting the power supply and attached circuit from overcurrent."
I am in no way any kind of expert on this but I have to think that there is something to the "dirty power" thing.
