Good old days

Simply step away that of which is ailing you, (the main rig.) Remember, "it’s a relationship" and you / everyone need alone time. Absence makes the Heart grow Fonder.

Get your daily fix and keep the Music flowing elsewhere in the meantime, return a rejuvenated man.

Works for me ......

Well, I wouldn’t go that far…..

Nor would I!  Frankly I think you are just basically a tad bored with your music, its all so familiar to you you just focus on the audio aspects. You love the music but you know it so well that unless it something new/different/outstanding you get bored with the music but not the audio. Time to refocus on things musical that you haven't spent much time on in the past. This is exactly what I had to do. I dumbed down my system some to get past those high(er) expectations and dug into new/different/unexplored music. Worked for me anyway. :-)

It is hard to get off the hi fi obsession and just go back to enjoying music for its own sake.  I think I was in the same place as the OP about a year ago and eventually I just decided eff it, the system sounds great, the secondary systems sound fine, bluetooth headphones and car stereo is also pretty good, and am back to enj9ying music again.
