MoFi 888 making me mad!

So are you going to keep them ? Also curious what you’re using for footers , have you tried decoupling? Regards , Mike B. 

Instead of trying to figure out break-in by brand/model, I simplify by using 200hrs as the my standard. One of my components was reported a 500hr break-in.  

I did have a similar experience with my 888's. I'd say I'm more patient but there is for me at least an18 day or so period where new has to become normalized to my ears and yes I played with placement. Good luck and keep them. I had tubes on mine and they were glorious and as well some Moon audio and some Accuphase and Pass; all great but Moon has the neutral and detailed sound that worked best. 

I bought a pair of Pure Audio Project Duet 15 Horn 1 open baffle speakers (half open baffle anyway as the horn is a horn) last fall and they took a LONG time to break-in...the 15" neo powered Eminence woofers needed to loosen up which was not surprising as an Eminence 15 in a bass amp I have did the same. They sounded great all along anyway so that was a good thing...the issue with break-in is when you prefer the sound of un broken-in things and have to get replacements every couple of weeks...but ya do what ya gotta do!

My Thiel cs2.4 speakers took roughly 100-200 hrs to sound their best.  From what I've read though it's important to leave speaker cables alone during this process. Of course experiment on positioning / toe in
