Furutech GTX NCF receptical break in, how long


Bought NCF with 6 day burn from seller. I have it burning in last 5 days on 2 cheap power bars with old desk top towers, fans, TiVo box, home theater amps. My amp and Preamp, phono stage and CD player are all tube so I don't use them. Ran system on outlet tonight and no bass, bright, sounds bad. First day with outlet it sounded very nice. Any owners of rhodium outlets can tell me what I'm in for time wise, or what to expect sound wise in next couple weeks, thanks

@ 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).
