"If you have a main panel with glass fuses then it's time to update the service."
I think this is a gross generalization at best, and at worst, advice that may end in degraded, as opposed to improved sound. Provided the size of the service is adequate (and this has nothing to do with whether the panel uses fuses or breakers), I'd much rather have fuses than breakers from both a sonic and safety perspective. That is not to say that dedicated lines are not a good idea, which of course they are.
