Advice on stand mount speakers

I am looking for my final speaker purchase. Giving up the chase.
I have a small listening room 13 deep x 12 wide x 8 high.
I have had several types/brands of speakers including Martin Logan Aeon I's Vantages, and Scenarios, Audio Physic Scorpios, and Kef 103/3's.
The Vantages are too much for the room. The Scorpios had too much bass but imaging was spectacular. The Kefs were very good but I had to augment the bass.
What I am looking for is a stand mount that has enough bass and has excellent imaging side to side and front to back.

I have been looking for used speakers in the $3500-$4500 range.
That includes a lot of good choices, Sonus Faber Cremona Auditors, Focal Micro Utopia, Merlins, Kef 201/2 and possibly 203/2.
I have no way of comparing these or any others you might suggest side by side so I am asking you all what your experiences/advice would be.
What are the strengths of each as well as weaknesses of them?
I realize the last octave of bass is out of the question but I want meaningful bass without having to resort to a sub.
Power will be provided by a Cary SLI-80 (40/80 watts) or a Phase Linear 700B (350 Watts) for now but will probably upgrade soon.
Thanks all,
Marlin
