The plated Leviton hospital grade will probably sound better than common household outlets. As long as you are going to the trouble, why not use the best? As I stated in my earlier posting, the Hubbell is the best construction, and the best sounding. If you compare the Hubbell, all copper construction with the Leviton, all copper, the Hubbell will have lower distortion, tighter bass and smoother highs. The Hubbell is available from commercial electrical sales outlets, and is only sometime carried by electricians. The reason? The buyer only sees a final bill for the parts and labor. If the electrician can use a brand that costs less, he makes more profit. Many electricians truly believe there is NO difference in any outlet, sound or otherwise, and are merely installing what they are instructed to do. If you cannot find Hubbell locally, Michael Percy Audio Products has them in stock, at a discount of $23.50 each. These are the correct ones for audio, and are rated at 20 amps. Mike can be reached at 415-669-7181 (voice) or 415-669-7558 (fax) he prefers orders via fax.
