Now, you said the magic word, fun. I remember a cartoonist that used to work for Stereo Review. Last name was Rodriquez?, and many of the cartoons were about the neurosis of the average audiophile. In one particular scene, here you have a guy watching a trace on a oscilliscope? mounted on top of each speaker. One trace was very slightly different than the other, but the look on his face was priceless. Let us not go there,,,it's not fun.
