OK. I have had mine for a year and I can assure you that they sound exactly the same. What has changed is that I have dialed in my room corrrection and that has made a huge difference. What is nice about these speakers is that they are efficient and have excellent bass extension. So, there is room for EQ and I can get away with a single sub because these speakers can go low enough to fill in a bass room mode.
Adaptation to speakers is a real thing. But it happens to the person, not the speakers.
