Just a couple of thoughts about the Oyaide's (the outlets and the connectors), they can indeed be 'too much of a good thing', specifically if your system is already very highly tuned and refined. And cryoing can exacerbate this effect. The reason for this should be obvious, in that much of the high-end gear we all use was not 'voiced' using Oyaide's or cryo'ed AC products of any kind.
In my main system, I use all cryo'ed FIM 880 outlets (the version prior to the current gold-plated models), and they are terrific. When I tried the Oyaide outlets (one of each), I found them to be a little too 'in your face', as well as obscuring fine bass differentiation.
I also had issues with an Oyaide connector on my (former) reference power cord. The owner of the audio salon that I've done business with for 25 years spoke very highly of the improvement the F1/M1 connectors made to the (name withheld to protect the innocent from going off-topic) power cord. He loaned me his re-terminated version of my PC, and It was frankly terrible. Shrill, spotlit, all of the adjectives typically used to define unnatural brightness. And bass? What bass? You could hear it only by listening for it. Frankly, it made my system sound like it was powered by an A/V receiver on steroids. After reviewing the materials used in the F1/M1 connectors, it makes me suspect that lowered conductivity/high resistance may be the culprit. Those connectors are made with beryllium copper, platinum, and palladium, all of which are poor conductors compared to copper, gold, silver or even high-cu brass.
Now before I get flamed, please note that I have heard Oyaide products in other systems in which they sounded fine, but in my highly-tweaked system, they were just too much.
