When I searched for my first high end speakers, I listened to the best I could find at audio shows (AXPONA, Pacific Audio Fest (Seattle, WA), T.H.E. Show (LA)) and brink and mortar stores. After finding the sound I like, then tried to reproduce it within my budget.
First create a list of the latest high-end speakers you'd like to demo like from Stereophile's Recommended Components and The Absolute Sound magazine's Editors Choice Awards (past issues: March 2024, November 2024).
Pick out demo CDs/Vinyl, then go to high-end audio stores and shows. I've visited/demoed many high-end audio stores in the Los Angeles area by Googling "high end audio".
