$20,000 is a great budget for sure, so here are some excellent all around speakers that work really well in most environments and are not too finicky. Some are open baffle, some are flat panels, some are horns, some traditional box speakers.....but all are brilliant.
Joseph Audio Perspective Graphene $20,000, Pure Audio Project Treo 15 $8,800 or Quintet 15 $12,800 (I prefer the horn version, but there are several options for tweeter/mids), Volti Rivals $16,900, Yamaha NS5000 $15,000, Fyne Audio F703SP $19,000, Revel Salon 2 Ultima $15,000, Sonus Faber Serafino G2 $22,000 on sale or Olympica Nova V $18,000, Diptyque DP140 $18,00 (If you like flat panels), and Linkwitz 521-LX Reference $18,000 with US shipping.
Best of luck to you, and let us know what you do
