Towers with massive dynamics & soundstage $3k?

Heya. Just looking to garner vouches for floorstanders up to $3k used/new that DO jaw-dropping dynamic crescendos and that have a wide and deep soundstage.

Theoretical shortlist is currently blank.

Weird sized room 15' x 31'. Assume beefy SS amplification. Mainly listening to symphonic classical and electronica!
