Looking in the $5K range used these certainly caught my eye:

And I don't think anyone here looks down on JBL, a classic brand that's made some amazing speakers. And if you think they sound good and maybe better than other speakers you've listened to then perhaps you can pocket that $5K or put it to upgrading other parts of your system? You list an MF M6i amp but how about your source? Cables? Etc?
