Setup Speakers Along Long Wall?

Ok..Added photo.

Current thinking..upgrade phono preamp to Rega Aura, or Whest with balanced outs and use Audioquest 3 meter XLRs and place integrated just forward of RELs.  Not ideal but this room is a bit narrow and Wilson likes 1/3 2/3 placement with listening at 1.1x speaker separation.

I should add that Shunyata Everest 8000 and Sigma power cables arrived today and made an incredible transformation of the sound.

I don't have cartridge feedback with turntable located as in picture.  I talked to the Wilson people and they prefer the speaker location as is, so I'm looking for a preamp with balanced out and 3 meter XLR interconnects.  My dealer suggested Whest, or Rega Aura and Wilson dealer suggested baby Boulder.  More bass traps on the way.

I'll be using a covering for windows, but nice view, so will only do shades.

Absorbers over speakers and to side and front of couch will be added once speakers are in place.

Calibration ..no.  I have an Anthem pre in theater room , so have equipment but can't get calibration file for microphone from anthem.

I appreciate and will try to take the above advice in that it makes sense to me.

The balanced phono preamp that I was looking at isn't available until November, so I'm going to buy more bass traps, lower my turntable rack and see if I can keep my interconnects short.

The problem comes from the energy put into the floor (2nd story) by the REL S/812 subwoofers.  I solves it by placing the turntable in the corner where floor vibration was at a minimum.
