Speakers that have sharp dispersion limits such as horns, planar speakers and linear arrays have large advantages acoustically in residential rooms. A properly deadened small room say 16 X 30 sounds better than a really big room with high ceilings because these rooms usually have acoustic signatures that are harder to get rid of, they echo.
There is more sense and more useful information in the paragraph above than in every thread and post on cable and fuses combined, and you could probably throw in 90% of the threads and posts on DACs and amplifiers too.
I am not saying that these types of speakers are without their own unique flaws as well, but far too much energy is spent painting the pig, not dealing with the little "gifts" the pig has left all over your listening space. Seems pointless to get hung up on things that "may" make a 0.01db, or a few microseconds of difference, and ignore the things that make 1, 2, even 10db of difference, and even 10's of milliseconds of difference.
