@jhills, "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.."
I bet every one of us here (excepting perhaps the most cynical of dealers), is familiar with that feeling.
With me, the audio OCD was at its worst some 15 years ago. After spending almost a months wages on a cartridge that was barely an improvement upon it's predecessor (which cost less than a fifth of it's price, and ultimately proved superior), I began the long slow road to recovery.
Of course, I'll never be cured, and don't want to be, but I do try to keep a perspective on all things audio. Friends and family help too. If that fails, I keep in mind the certainty that music is there to be enjoyed, not analyzed.
The Beatles 'Ticket to Ride' will still sound good on any system,
