What are the principles of soundstage reproduction? Is it room placement? Is it speaker fidelity? Is it room colorations? I am having a discussion with someone on another board and he believes that soundstaging is irrelevant of the speaker's fidelity (or acoustic capability) since if positioned correctly, ANY speaker will give ideal soundstage. He doesnt buy my A/B of two speakers with the same equilateral triangle positioning and having the tweeters of both speakers at same height. I used the same amp for both (and at same volume). Also, the room was acoustically treated. One speaker.... CLEARLY had better soundstaging... in a sense that it sounded even and not boxed in. The other didnt have as good a soundstage (both width and depth) and sounded relatively boxed-in. The guy doesnt buy the fact that the first speaker provided a better soundstage... he says reposition the other speaker. However, how come all speaker comparos are done with the speakers IN the SAME positioning configuration??
