Where should I Go Next?

Thanks to all for the comments and suggestions. I was most curious if my cabling was sufficient. 

I love the Focal speakers and won't be upgrading those for some time.

I think I've done everything possible with speaker placement in the space I have available.

As for vinyl cleaning I have a Degritter MkII, a Record Doctor X and a Keith Monks Discovery One.

They get the job done in every way I know how.

My LP collection is nearing 3000 and I've been slowly selling off some of the records that need upgrades in condition and those that I never listen to that have no monetary value.

To those who suggest a speaker upgrade, what would you recommend? It won't come soon but advice is always appreciated.

Have you sound treated your listening space with scatter and/or diffusion plates? They’ll improve whatever your intended sonic endgame and are portable.

I do have quite a few diffusion plates...as many as my wife will put up with. Some on the wall behind the speakers and some on the back wall behind my listening chair.

The side walls are pretty far away from the listening space due to the layout of the room.

your speakers don't have weaknesses so it would not be simple to upgrade. Still they are definitely your weak link. (Yeah, contradicting sentences.)

I'd say if your budget was ~3K, used, you would have a few amazing options.
