Furutech GTX NCF receptical break in, how long

All was well Sunday, Monday. Last night bass was thin highs unlistenable. Didn't spend much time listening just enough to see what's going on last few nights My system is slight on warm side of neutral. I have not stopped burn in. I'm not sure what's going on but I'm to the point of boxing everything and dropping it off at Goodwill. I'm wondering if a furutech gold added to the mix may help in the long run.

@ paulcreed, Been awhile, need to mention that you need to run system 12 hrs and then turn off at night, do process all over again each day, this needs to be done after 450 hrs, be patient my friend, I would like for you to keep me informed here with progress, remember, the extended high’s come in at 700 hrs like a brick up side the head, believe me, you will know when the treble detail kicks in.

Will do audiolab, had some time to kill on road this morning and called furutech dealer I bought from. He said at least 6 week burnin and it is normal for it to swing like this even with 450 to 500 hours. Loss of bass etched highs. Last night the highs were almost the worst I've heard during this process, like broken glass. He also mentioned these outlets are very system dependent on how they react. He builds his statement power conditioners with these NCF's outlets so he has to have some experience and feed back from customers. Will try 12 and 12, what a crazy hobby!

Paul, I have experienced that harsh broken glass sound as well at times where I thought it was burned in.  It is also like some evenings it sounds okay but the next day it will be really bad and un-listenable.

What do you think is actually happening during this "burn in" process that would explain the purported sound changes?

Outside audiophile lore, I've never heard any electrician or electrical engineer (who isn't selling high end audio products) say any receptacles need "burn in" for any reason.

So I'm wondering what the actual technical reason would be for this "burn in" phenomenon and why it would alter sound.

(In my own experience, I've never heard a difference whether I've changed the outlets where my equipment was plugged in, including moving to a new dedicated outlet, or whether it's plugged in to my Furman power conditioner/bar).
