As a general music enjoyer (streaming from spotify) is it worth spending +600€ on gear?

I enjoy music listening, but I'm not a hardcore audiophile.
Convenience is still very relevant to me.

But I need and want to replace my old speaker setup with something more special.
I am eyeing a combination like WiiM Amp + Elac Debut 3.0 Series (maybe Dali Spectors, maybe Q Acoustic 3030i, maybe...)

But I wonder:
Is it even worth for a guy like me to spend 600€-700€ on a speaker setup.
Will it make a noticable difference?
I might use other sources later but for now it will be Spotify 99% of the time.

I currently use a Panasonic SC-PMX94, nothing out of the ordinary.
