Hello Phillyb, What you're describing is what I ran into during the summer last year. I put the R-1's on a fridge, tv and freezer for about 2 weeks and then installed them in my system. I had three R-1's and was also running the WPC-Z outlet covers. The R-1's were very open sounding and a bit bright initially. The mids and bass were OK, but not up to the Wattgate 381 gold that I'm used to. I had and still have one Isoclean duplex outlet that I use on my sources. I left the R-1's in for about three weeks. At the three week mark, they had become more balanced tonally, but sounded just a bit dull. At this point, I put my Wattgate 381gold outlets in my system--(one for preamp and two for amps) to see what kind of contrast that I had between the two brands of outlets. The Wattgates were clearer, more dynamic and more extended at the frequency extremes. I just left the Wattgates in and sold the Oyaides. It is possible that the Oyaides have a very long breakin. Wattgate 381gold have a 300+ hour breakin, so maybe I didn't give the Oyaides enough of a chance to burn in. Not including the burn in on the fridge, tv and freezer for two weeks, I figure that the Oyaides had about 200 hours on them when I pulled them out. I'm thinking of getting one R-1 to try on my preamp again, but this time I want to leave the Oyaide on my fridge for at least 6 weeks. If you're handy, I'd put them on your fridge and freezer for over a month and try them in your system again then. Running a osscilating fan through your outlets 24/7 would be a big help if you want to leave them in their present position. Just my .02 cents worth.
