Proclaim, I have not had any experience with the Oyaide, but have certainly read a lot of favorable remarks about these receptacles. Unfortunately, there do not seem to be many people who have compared the Oyaide to, say, a cryoed Hubbell 8300H or cryoed Hubbell 5362. The one person that I know of who has both the Oyaide and the cryoed Hubbell 8300H (from Albert Porter) is Audiogon member Maxgain. I believe he just recently acquired the Oyaide and am not even sure whether he has done a "head to head" comparison with the cryoed 8300H, but it may be worth doing a member search here for him and e-mailing him with a few questions. He tends not to post much here anymore, but I'm sure he'd be happy to give you his impressions and some valuable info. If you are using stock receptacles, I would be pretty shocked if you would not receive a pretty decent performance boost with the Oyaide and certainly believe strongly, from experience that you'd definitely get a performance boost from either the Takefive's or Alberts 8300H units as well.
One thing that I would suggest to you, particularly if you are buying new cryoed outlets is to make sure they are fully burned in before inserting them into your system. As difficult as this is to do (being anxious to get them into your system right away when you buy them to enjoy them), I'd recommend installing them on a fridge or chest freezer (if you've got both those items and you've got two receptacles, you're all set!) for between 4 & 6 weeks, switching the plug from the fridge/freezer about half way through this burn in period from one half of the receptacle to the other. The high current draw from the compressor kicking in on these items will give you a much more effective burn in than any you can create running just your system on these receptacles and it will allow you to hear them at their best when you then slot them into your system. All receptacles (IMO) require burn in, and cryoed units can be particularly strident in the burn in period, although they may well be better sounding in some areas than those you've replaced.
