There is no such thing as a forever component… well for me there may be… I’m 70. But, in general no. But on the other hand you can buy ahead. I am willing to bet that my Aurender W20SE will out perform the contemporary BlueSound for at least 20 years. My Aurender performs at the level of my great vinyl system. So, I get incredible performance now… that will likely last past the end of my life.
This has been proven to me over and over again since the 1980’s. You get an audiophile piece of equipment and it will outperform other stuff for a decade or more and lower end stuff for much longer. The quality of the design and materials in a high end piece of equipment just isn’t easily reproducible. With the movement away from globalization this gap is likely to get larger.
