Furutech GTX NCF receptical break in, how long

I currently have about 20 hours on the GTX-D NCF. It's true that it sounds great during first few hours. It's sounding not very good at the moment with a flat sound and rolled off treble. I can't wait to get this thing past the 500 hours mark. Still a long way to go 😭

It sounds terrible between 20 to 50 hours. I hope it will sound better approaching 100 hours.

Right. I'm not sure if some of you guys are exaggerating on the numbers. Currently I'm between 100 and 150 hours. I would say the sound quality is great after the 100 hours mark is passed. No more fluctuations.

Right, I can’t believe I’m updating this thread. A little update. Just today I’m hearing a change with the system. The bass is hitting lower and sounds fuller with better definition and detail. More defined. Midrange and treble also sound fuller and fleshed out. The highs sound silkier and more illuminating. I can’t believe this. I thought I’m not getting anymore changes with the system but it looks like the Furutech NCF receptacle really needs time to break-in.

I’ve made some calculations and so far I think I have about 300 hours on the outlet. If this thing will only give its 100% after reaching 500 hours as claimed by few here, I can’t imagine how my system would sound like then. At the rate I’m going I think I need 2 more months to get to the 500 hour mark.

Thanks for the update.
