I’m 70 now. My experience has been there is a pretty direct correlation between weight and sound quality, the heavier the better they sound… one that has not recently reversed. So, I have been enjoying the best system I have ever had, and the heaviest.
The only changes I have made is I don’t lift them. I use my brain instead of my back on how to avoid it. My dealer moves them… there are other options. In my old age, the last thing I want to do is compromise the sound quality of my system.
