This will be a significant upgrade for you. If you don’t like the price on the audiophile outlets, Hubbell 5362’s are very good.
New Electrical Circuit
I have an older house with open circuits so I am wiring a new dedicated circuit for my audio gear. Before I do so, would it be very advantageous to bump up the quality of the outlet and / or wiring to improve quality or is this overkill? Has anyone done this in the past and what would you recommend?
