Ok, this may be a little off point, but you'll see - it ties in.
I have a sister that is clinically OCD. She will sometimes clean and re- arrange her house until she literally drops from exhaustion. She got this thing, awhile back, about collecting rocks to line her driveway. After collecting a good number of various sized and shaped rocks (on every walk she took, on every ride she took, from neighbors wanting to get rid of their rocks, etc. etc.) ranging from 20 - 40 lbs. she got enough to nicely line her driveway. Her OCD would not let her stop at that, now she has a one acre sized yard covered with pile after pile of rocks. I jokingly told her that she should contact Mr. T. and offer to build his wall and could even bring her own rocks - don't think she appreciated the humor.
My point is that, we as audiophiles, may get a little OCD and let a continual need for upgrades, tweaks and changes, take the place of periodically just sitting back, for a bit, to enjoy the music.......Jim
