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

{For you to believe that excellent manufacturers build gear to minimize useful life prematurely is misguded.} Planned obsolesce is a thing I didn’t invent this or imagine it, it exists. Audio products are mostly made from parts from many manufacturers. Manufacturers use planned obsolesce for many reasons and not just to milk you for more cash some things you don’t want to last longer than needed. But most all products factor it in. Why are audiophile products somehow not part of this? Do they all agree with suppliers to forgo any planned obsolesce? Review this and tell me that it doesn’t apply to audio.

1. a policy of producing consumer goods that rapidly become obsolete and so require replacing, achieved by frequent changes in design, termination of the supply of spare parts, and the use of nondurable materials.

What is your point? Buy an Audio Note Ongaku today versus a twenty year old Ongaku. There have been running changes but the twenty year old amplifier remains an exceptional performer and is completely serviceable. If you purchase compromised products then its a choice you make.

You can still get 50 year old krell amps serviced,  and I'm sure pass labs services their older equipment. Try having a run of the mill mainstream piece of audio equipment serviced, usually doesn't happen.

{a policy of producing consumer goods that rapidly become obsolete and so require replacing, achieved by frequent changes in design, termination of the supply of spare parts} this describes a good portion of the audio market sure not all nothing is an absolute, and one can always find an example outside of this but that doesn't eliminate the basic premiss.

So @johnk to clearly answer your original query...excellent gear is built to sound and perform excellently. Your premise that most things have a planned obsolescence or worse, that it is designed to impress and then sit around not being used is inaccurate.
