How do you know when a stereo sounds good?

 This post brings up something I often wonder about. 

Best song title tie in- "What kind of fool..." 

The other question I have is why do you sit down one day

and absolutely love the way your system sounds yet the

next day conclude it is nothing special?

How can I tell if my system sounds good?

1. Ask my spouse if the system could use some tweaking

2. Close your eyes, Lean forward in your chair. Take a listen

3. Listen carefully to the sound made  while it

   hits the pavement from two stories up.

4. Gather some blind people to your listening room

    and perform a listening test. 

5. Consult the 8 Ball!
