I'd also agree. But I do think it's possible to have a very revealing system and still listen to sub-optimal recordings and enjoy them. It's also highly dependent on the genre of music one listens to, I've found classical and jazz/blues to have the greatest delta of recording quality between poor vs. excellent.
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.
