Best Speakers for a small Nearfield room, budget at most $10000 (used is also ok)

Hi guys, I am a newbie here and am searching the best speakers in a small room (my room is about 13’ x 10’).
Consider a pair of bookshelf or small floor standing (like Magico S1 mk1?). Those speakers will be placed near the corner of the room, may be I will prefer a sealed case.

I listen to female vocals, jazz and light original sound tracks at a relatively low volume. Since I am transferred from a headphone system, what I really care is the musically and smoothness of the system. Any suggestions?

BTW, I am in USA now. What kind of brands that could be easily found in Usa?

Now I am looking at Magico a3 (There are multiple driver for a3, I am afraid it is an overkill for my room), Magico a1(seems good), Raidho xt1, xt2, used c1.1 ?

Kef reference 1 is a great neutral sounding reference speaker that sounds great at all volume levels!
stay with 2 way monitor Or single driver with front port or sealed box .
my room smaller than yours and currently use Harbeth M30.1 .
we have similar taste for music .
My room is a touch larger than yours and I replaced Harbeth 30.1’s with Magico S1 and they are better performers but do cost more money.  Other than room size what equipment are you using?
I have Focal Sopra 1 in similar situation. I would also look at Wilson Audio Tune Tot.
I used a pair of Totem Model 1’s for years in a small room. I then moved up to a pair of Totem Mani II’s which require a powerful amp. Both speakers need stands. Another option which is a little more money are the Usher mini-x stand mounted speaker with the diamond tweeter. I have multiple pairs of usher speakers in my home all with the diamond DMD tweeter.
