The argument against upgrading

Making a change to tweak the sound is par for the course.  What has changed that I think many still are not aware of is the tools like DSP available these days other than changing gear, which is still part of the equation when needed. 
 

DSP tools like those provided in an app like Roon for example  provides incredible flexibility to tweak sound as needed or desired.  
 

It’s like seasoning the soup in order to make it just right. No need to change the basic ingredients that go into it if high quality and mixed just right to start with.  
 

Why rely on the hardware alone to make all the decisions about how things sound when you have the tools needed to tweak it just right as needed, once one gets up the learning curve of course. It’s a very worthwhile exercise for all I think. Plus if you don’t like the results it’s easily reversible with a touch of a button and you can start over again from scratch as much as needed for no additional cost.

If your system pic is current, then the best ‘upgrade’ would be room acoustics.

I actually did not understand the point of your OP.  Why would you stop “getting into” certain songs if you upgrade?

The point I was trying to get over is that the experience being absorbed in music doesn't necessarily depend on sound quality. Another way of putting it would be suspending disbelief. Once I'm pulled into it, I may not care about quality because I'm just enjoying the music. 

Very likely improved sound quality will make it easier to get there or make a wider range of music accessible. But still not necessarily enhance the experience of listening.

Of course, this may be different for difference listeners.
