There is one thing above all others that makes a system "good" or makes it "not good enough" and it doesn't appear on your list, Bill. Of course that's not surprising because it's something so basic that it escapes most everyone's notice.

That one thing is actually comprised of three elements - namely the Attitudes, the Beliefs, and the Expectations of the owner of the system. These three are what I've dubbed the ABEs, and they play the decisive role in separating the satisfieds from the dis-satisfieds in the worlds of audio and video (not to mention everything else in life).

In the final analysis, it's one's ability to control their personal ABEs that ultimately determines whether they have a good audio or home theater system or they have a system that is not quite good enough.
