Most people do not realize how bad a recording can be until they hear it on a great system. A good system will make good recordings excellent and bad recordings unlistenable. I love listening to great recordings on a great system as I find myself enjoying artists and music I never considered previously. IMO the recording and the system go hand in hand.
How much is about the recording
For myself, I'm comfortable in knowing I have arrived. At my own personal audio joy through years of empirical data and some engineering knowledge and application. I just wonder how many like minded individuals find as much joy in finding the best recordings vs the perceived next best gear. Peace.
