MRI grade vs Hospital grade electric outlets
I know both have been suggested as an upgrade to the run of the mill cheap outlets. I also know there may be "even better" outlets. I know the MRI grade has non magnetic metal components. Bottom line, does it make a difference one can hear? I have about 1/2 dozen Hubbell 30 Watt hospital grade outlets. Got them fairly inexpensively. Are the MRI grade worth the extra $$$?

@kavakat1, As for the Hubbell hosp grade outlets, what model/series? Old stock HBL8300H Compact slim body? A very good duplex receptacle. Non nickel plated brass contacts with a non nickel plated supporting back strap. Example in brown: https://www.zoro.com/hubbell-wiring-device-kellems-receptacle-duplex-20a-5-20r-125v-brown-hbl8300h/i... The old style Hubbell HBL8300 standard body hosp grade outlet has nickel plated contacts and a nickel plated back strap for corrosion. The nickel plating has ferrous materials in the nickel. Ferrous material can and do affect the SQ of a sound system. Avoid any outlet that has a galvanized steel supporting back strap. Bad for the SQ of an audio system. Watch out for newer Hubbell 8300 hosp grade outlets. The back strap is made from nickel plated steel. Garbage for audio. http://ecatalog.hubbell-wiring.com/productinformation/specsheets/3A/Live/PDF/HBL8300H_cart.pdf To check for steel or ferrous materials use a strong magnet. . |
