My opinion has mostly been stated above but for what it's worth: In general hearing more systems provides more data points to assess what you like / dislike and want / don't want based on your listening preferences. Hearing higher end systems exposes you to data points often with higher audio quality which should open your scope of possibility to what you want and what to potentially achieve. In my experiences with high end systems (>500K) I often walked away with particular areas that I aspired to achieve (ultimate clarity, dynamics, etc.) but very few systems checked all the boxes in terms of an ultimate system. My experience tells me this is more about room treatment / placement or lack thereof.
