Guidance

First get the AC power as clean/stable and quiet as possible. Then work on room acoustics and finally vibration control/better audio rack etc. Now you will be able to better evaluate the synergy of your system and find/correct the weakest link. I realize for many these steps are not the "fun" part of HEA  but they are a necessity if you want to take this hobby on a serious level.

Thanks @deep_333 

Thanks @zlone ... I'd say 95% of my music is digital through Qobuz, 5% is analog primarily because there have been situations when I put a record and start listening and all of a sudden I need to go break a fight (its a lot of fun with 3 teenagers) and before you know your nice cartridge is scratching middle of the vinyl :) 

@lak @hilde45 thank you both too ... gives me some direction to focus on as opposed to losing my mind over small tweaks which might end up being not that impactful

Thanks @tomcarr ​​​​@dayglow 

this is a great hobby!

The guidance I give has been provided in many similar posts - that making incremental improvements or optimizing current systems needs to start with listening to acoustic and amplified music in intimate venues and establishing your perception on how recorded music should sound on your system.  Then you should choose reference recordings you feel approach your perception on live music best.  The next step is to listen to your current system using those recordings and establish a goal for improvement.  Then, when you audition equipment, ancillaries, and tweaks, you can determine if you have met your goal.  
You seem to have established a goal to improve the soundstage and improve the weighty-ness (image density) coming from my current system without a large spend.  I will give suggestions from my experience:

1. Optimizing speaker placement.  I have found small adjustments toe in, separation, and distance to listening position can snap in staging and density. 
2. Room treatments. 
3. Power conditioning or regeneration:   A good power product will improve many areas of SQ including staging and imaging by reducing noise floor. 

However, to get a transformative change, and reviewing your system, a capital expenditure to improve the source components (streamer and DAC) and the amplification (pre and power, or integrated amp) is required.  I would add a Burmester 082 or 032, AR, or Hegel to your list of integrateds.  All are known for image density and staging.  The Wyred4Sound 10th Anniversary, Bricasti M1 or M3, AR, and Mola Mola Tambaqui are also known for staging and imaging.  

+1 for adding a pair of REL subs. The high level connection which attaches directly to your speaker terminals on your amplifier, allows the subs to blend seamlessly with your speakers. I recently added a pair and I consider it to be the best bang for the buck upgrade I have made.
