I experienced exactly this in the past, and yes, it didn't last. In recent years I've not experienced anything less than a fully immersive, pleasurable listening session, I both consistently admire the sound quality and become fully involved in the music.
Has this ever happened to you?
Has it ever happened to you that you sit down to listen to your system one day and just go “Wow!”, THIS is the sound I have been looking for? I have recently been hyper focused on incremental improvements that I have been making, and was really just listening to “the sound” of new components or cables but not actually listening to the music. Recently, I sat down to listen to music, and I am hearing exactly what I had hoped it should like in my listening room. I am feeling something new for me in this hobby for really the first time - contentment.
Curious the hear about your experiences.
