Are audiophile products designed to initially impress then fatigue to make you upgrade?

Johnk I favored going to Axpona and to my audiofriends ,so I can listen to different systems , it’s an opportunity to find out what sounds your ears preference.Reading helps not much.Before one system really does impress me on the first day.I will go back to that system for the next 2 remaining days.Many times I end up not liking the system on the 3rd day.You will know on the third day if indeed that’s what your ears prefer.

Any 

As you learned and improved your listening skills, and your finance improved? You will more likely do upgrade.
