AKUS - So Long So Wrong- Time to Stop Upgrading?

Just purchased this LP based on the fabulous reviews.

I would have to say that the song: It Doesn't Matter Anymore is the best sound I have ever heard on my system. Her voice and the instrumentation sounds perfect to me. Maybe the slight reverbation helps. Worth buying just for this song.

My point is that everyone worries about the equipment when in my opinion the engineering of the record itself is a major limiting factor in sound quality. In other words until I heard this song I didn't realize how good my system was. If this song sounds great to me then why spend thousands more upgrading?

Unfortunately it is records themselves and CDs that need to be substantially improved. I am sure it would sound better on other systems but at how much expense? I probably will upgrade my cartidge (the Lyra Lydian) which is probably the weakest link in the system but again I am 100% satisfied with the sound of this song.
