Any one try the new Synergistic Research BLUE UEF Duplex receptacle?

Could someone please explain why a fuse or receptacle needs to break in? I'm thinking it has more to do with the return policy of these over-priced gimmicks. Just wait more than 30 days and it will sound amazing! And... the window to return will have passed. 

Also, the only job of the entire AC power feed is to supply voltage and current with minimal sag or reduction during transient demands of the highest power consumers in an audio system like amplifiers.

If I may suggest a far cheaper and much more effective method to improve sound quality. If you're reasonably handy and careful you can run a dedicated branch circuit from your power panel to feed your amplifier(s). This will result in much less droop in the voltage when amplifier demands are high. This will then result in better control of your speaker drivers. You may even notice that your house lights don't dim when you really crank up the volume. A nice side benefit.

I'll admit that I've fallen for the placebo effect a few times in my audio adventures. Caveat emptor and all that...

I completely agree. I wish I didn’t believe in break in and/or could not tell the difference. It sometimes goes through many changes - better, worse, then better again, etc. I wish it was placebo. It’s easy to blame it on placebo when one does not believe in break in or cannot tell the difference. Not much more to say - neither side will convince the other.

I sprung for a $19 Pangea outlet recently (my bedside Schiit Magni 3 headphone amp has what seems like a 14 lb power supply) as it was cheaper than the PS Audio ones I'd previously installed elsewhere...I'm mostly interested jn the grippy-ness of these things (and they're both simply a more substantial design than the crappy el cheapo standard ones), and the Pangea is certainly grippy...well done. The PS Audio outlets took 4 minutes to break-in (actually one was 4 minutes, the other one was closer to 18 seconds), and the Pangea sadly never broke-in at all, but does convey electricity from the wall cable to anything plugged into it which is all I ask of it...that and the grippy part.

Exactly. And the irony is that the reasoning that leads to the claim of placebo effect may in fact itself be the result of placebo effect.
