Ever sit down to listen and just say wow?

Ever go through a period of extended tweaking of multiple components of your system and get so focused for days, weeks or months on trying to improve different elements of the SOUND that you stop actually hearing the MUSIC.  Then you sit down one day to actually listen for pure enjoyment and say holy crap, whose system is this? I want to listen to ALL MY MUSIC RIGHT NOW.  I am sure this phenomena happens all the time to Agoners, but it's a wonderful thing.
