So I am trying to understand this topic better...

I am a guitar player and I always prefer the sound of older "broken in"
speakers over new identical ones. They have all these new re-issue speakers
but I still prefer to buy used ones on ebay. The new ones sound less
resonant to my ears, especially when pushed to gig levels.

Is this difference an actual acoustic difference or psycho acoustics? is my
mind playing tricks on my ears????

Thanks, all comments welcome... curious what you all think,
Garrett
