Every speaker I bought did something I liked that after time wasn't enough to keep the illusion alive, that said the speaker still excels at what I initially liked about them and each following speaker pair I buy gets me closer to all the things I liked best about each pair.
I think some people find speakers that check more of their boxes and get them closer to what they think they are after....so they keep them for a few years and then realize they are listening to music less....maybe looking at their cell phone more while listening.
In my head I just keep going back to the ex girlfriend analogy.
Yes, especially the unrefined trashy one that did a few things great. ;-)
