Glad to see how many speak of Oyaide R1s. I bought 2 for my soon to be dedicated AC line. I also got 2 very thick non ferrous faceplates. The R1s and faceplates were about $600 each. And on the recommendation of Joe at the Lotus Group, 50’ of the very special three conductor copper cable. $3300. Waiting on my electrician who will be about another $1K. Hope that the result will be worth it. Seems that since power chords make so much difference, the Oyaide cable will be significant.
