$20k speakers that really impressed you

Not sure they will be $6k-$7k in a few years, but the Legacy Audio Aeris are just phenomenal when set up optimally.

Thiel CS 3.7 ($6K now)
Kef Blade 2 ($13K now).

 I listed used prices.

I guess, audiophiles are hard to impress, $20k speakers are nothing.

Lol, they’re not $20k, but the new Revel F228Be that I heard at AXPONA impressed the heck out out of me!  I think used sets can now be found around $7k.  I recently was able to audition a set of Rockport Aquila in Houston, which I think originally sold for $45,000 and are now available for $12,900. Yeah, they sure impressed me, but man they are big speakers, too big for my room.
