I have Sonus Faber Cremona which were introduced in 2003. SF has gone through several newer models since. I still like the original ones. Over the years, speaker design has changed. Many believe my Cremona are "colored" because they have a slight rise in the treble. But, they sound very good to me. Later versions have done away with the rise and have strived for more detail. To me, the new ones sound too clinical, without the richest of my old speakers.
The point is speaker design does change over time. But, it is up to you to decide which you like best. That is one reason there are so many speaker companies. Different speakers sound different. You just need to pick what you like.
