How good is good enough?

its "good enough" when I can simply sit, listen to music, and enjoy it.  

When I was in the gear-hunt phase, over a few decades and more, I think my objective then was more about trying and comparing different components. And I realize today - this phase was less involved in listening to music, and more more about new learning around how different level of qualities of gear can sound. 

Kinda depends on what headspace you are in at the moment too. Eventually got burned out and learned to enjoy more than a few components that sound "good enough".  After this point, any new change just became "different" and not necessarily better. Had to kinda stop there.  Back to listening to music now :)  

@rvpiano It’s very easy to go down the rabbit hole if you listen for defects instead of listening to the music.

Agree with this statement by rvpiano. Also, I'm observing once again why its important to give a new system or new components time to settle in.  Its not always  about 'just getting use to it". There can be change that occurs, given the chance. 

Patience helps from jumping out of one rabbit hole to another rabbit hole.
