I am a collector of full range speakers.  A good pair of vintage speakers with modern dsp can absolutely make newer speaker seem silly to buy.     I’ve yet to hear anything that will touch the larger dunlavys.p, For 10000 or less. Or the big old t... 
Best used speakers under $10000
Dunlavy sc 5s.    There is a pair for sale now.      Or magico 3s or 5s if you can find used.    Higher end legacy speakers .    All these sound clear and can punch as you describe.

Older Electronics - When to cut bait? Your thoughts?
