Speaker positioning games. Where can I go from here?

Last Thursday night I was messing with my speaker positioning. I’m nwver happy with the bass but I am barely into building my endgame system so I think some of that will worked out.

anyway, I moved my speakers (Focal 907v on stands) from 13” (back of cab to front wall) out to 22”. Bass is lessened but it’s most noticeable in bass attack. But there’s a fullness I didn’t expect.

I then toed them in which really made the vocals pop into that center position and all around imaging is much improved. The left speaker is 40” from a wall of windows and the right has nothing next to it for 13’. For the toe in I left the outside corner of the cabinet at 22” from the wall but rotated so the inside rear corner is now 21.5” from front wall. I think this improved imaging by lessening reflection on the left side.

I sit on a couch with a table between it and the back wall. My ear is ~18” from the back wall (drywall). The drivers are 91” apart and 98” to my ear. I think lessening early reflections and some combing has made things sound better.

My system build is glacially slow. So far I have the power amp I want and that’s it. All other pieces will be swapped out and sold as I replace them. My plan for this calendar year is to replace the Project DC with 2M Blue with a SL1200GR with possibly a Nag MP200. Next year, maybe around March replace the current line stage (Schiit Sys-temporary) with an Odyssey Candela (tubed line stage) and Buchardt S400 speakers in the summer. My feeling is that these first 2 pieces alone will really bolster my bass I response.

But in the meantime. What other positioning tweaks can I try? My room is basically a horizontal rectangle with the living room/listening spot on the left half with the rig on the long wall.

thanks.
