Most of the times if we are bored by the music/sound of our system room it is because we had not reach the optimal way to install or as i say embed the system rightfully in his three working dimensions.
The only exception is bad design of some gear pieces or bad synergy...
No system with synergy well embedded acoustically at any price can be boring ...Music well done acoustically dont bore and we forgot the system it become immersive . A bad system for many reasons can bore.
My thrill come from music with immersive sound. My thrill is not changing the gear. 😊 The only source of boredom cannot be music it is a lack in one or all system working dimensions or a lack of gear synergy.
This lacks can manifest in 2 ways : frustration when the lack is evident as a defect or boredom when the lack is not located or identified as such by the owner nor evident ...
I think you reach a point where, you become so used to a particular sound that the thrill is diminished. That’s when you begin thinking about changing it up again.
