Soyez le bienvienu, Roger!
I'm not familiar with your amplifier, but I have a colleague who is experienced in building amplifiers using smaller NCore modules, so I'm confident that your amp can easily drive a very wide range of speakers.
Do you have a ballpark idea of what your living room size will be?
The room will be 5x7m. Speakers will be along the 7m wall, in the middle so no too close walls on the sides.
Will your living room be open into other rooms ("open floorplan")?
Just a normal room.
What attributes do you most want from your speaker system?
Actually, I use a passive preamp (tvc) which is very transparent but the max attenuation is - 48db. So I am afraid if I add high efficiency speakers that the min volume might be already too load.
Are there areas where you would be willing to compromise if necessary?
Not more than 10k 
Are you most interested in how the speakers sound when in the optimum "sweet spot" location, or in how they sound throughout the room, for people who may not be near the "sweet spot"?
That s a good question. I like both. On the one side, for critical listenings and testing gears, I am happy to enjoy sweet spot. But for everyday use I like something that make you feel the band is in the room. Plus, I often work at home, with classical or electro music at low volume, in that case sweet spot is not that important.
What sort of constraints (size, placement, etc.) do you need to take into account?
My wife would kill me if I buy big magnepans... Something below 1.4meter high would be great. I think they will be max 1m far from the rear wall.
What speakers do you have now, if you don't mind?
Currently I run neat motive sx2
What are some other speakers you like a lot?
I lack of experience, I downgrade my previous B&W CM10 to the neat motive sx2 as I found were better for my room and my test. A friend has kef reference 1 speakers and another has proac d20r. They both different but I like both... When I was a kid, my dad had bose 601 speakers. I liked them a lot as well. So I don't know exactly how to answer.
Is there anything else important that your speakers should do, or should NOT do?
The only thing which is important is that the speaker shall be good at low levels.
You DO NOT have to answer all of these!
Merci beaucoup!
