Stehno: One outlet I sent to Ed only had one set of connecting screws. I'm assuming he took the outlet with both sets of screws and removed them so that both outlets are identical to you. That means that there could be some confusion with respect to which screws are cryoed and not cryoed; ie. you could be listening to a cryoed outlet with non-cryoed screws and vice versa. Personally, I doubt whether that could have much of an effect on the outcome. I had not used either outlet in a very long time and can't even recall where exactly I had them in use. I believe Ed ran them on his refrigerator for a few weeks, but not sure whether he did each half of each receptacle. If there's any doubt, you could simply pop each one on your fridge or freezer with 3 days or so on each half and I think you'd be fine. Frankly, I'd just go ahead and use them at this stage. Obviously with your wiring situation, you'll need to use both sets of connecting screws with each outlet. Have fun and see if you can hear the difference.
Ed: just out of curiousity, seeing that you sent both outlets to Stehno with only one set of screws in each, did you mark the receptacles at your end before sending them off to identify the cryoed one?
