To the above I would just add that the room in which a system is to be heard should be factored in when selecting speakers. I know that one's room is subject to change but there is a principle that won't fail you. Speakers need to be at one end of an equilateral or equidistant triangle with your listening position at the triangle's apex on the other end. Now comes the hard part, well away from your room boundaries. And if your listening in the near field as I think you might be if you follow the above, I think it's important that you audition speakers with their drivers tightly grouped. I have a preference for two ways for coherence and imaging free of their enclosures. That ain't all. If possible, take anything massive or bulky out of the room and cover the floor. The side walls should mirror each other if at all possible. Open legged tables. And no queen anne or high back chairs unless you are seated against the back wall, preferably not, in which case there may be a theoretical advantage. All the best.
