So... coming in late and reading the entire thread at once, I think the message is that "hospital grade outlets give cleaner power because they are wired up to cleaner power in the hospital". The only benefit of the outlet itself (without the special wiring) is better plug retention and better ability to survive cola spills without disintegrating into sludge.

Spending a few $$ making sure your HT system isn't on the same circuit as the air conditioner, florescent lights, garage door opener or aquarium pump probably IS worth doing.
