Start with the room. This defines what speakers you can fit and work with. How big is it? How is current damping? Can you treat it, etc... Once that is defined I suggest selecting a speaker as your choice will be a function of the room and your taste both visually and sonically.
Once the speakers are selected, you then need to wisely select components to feed those speakers to achieve your perfect sound.
There is an infinite number of items available and if you just buy expensive stuff without thinking of synergy, you might get lucky or you can end up with a sad system. I have heard some very sad expensive systems and some modestly priced systems that are jaw dropping. Key is synergy.
Going to listening rooms is fun and can give you ideas but more than anything, the speaker needs to fit the room.
