Are advances in technology making speakers better?

So maybe I can upgrade my B&w 802 d3 to d4.  Not sure they're all that much better but I may do it.  Hate getting rid of the d3 speakers, maybe I can put them in the back of the room as rare speakers.

Maybe I buy Magico speakers.  Always been curious about those. The really expensive ones are really big. 

The rest of my signal chain is in great shape.  I invested quite well in all the stuff supporting the speakers and i can now accommodate superior Magico speakers. 
 

My philosophy is to avoid the upgrade cycle by buying top of the line products.  My speakers were not top of the line and I need to change this.

Most important component in a system is the speakers which are supported by a cast of characters that live in a rabbit hole.

I wonder if people really understand what good imaging is and what good soundstage means. These terms are really thrown around quite liberally.

And balance this against a well recorded piece of music versus mediocre. I think a nicely recorded piece of music achieves more then spending thousands and thousands on amplification and speakers.

It’s a mess and spending tons of money to address poorly recorded music doesn’t solve engineering shortfalls.
