wordsmithing aside, i think we know what the op is asking for

leaving aside those designed to produce the sound of a live classical performance, the speakers out there that have that 'live performance' type of feel, sound, with attack and dynamics (if not as much a sense of control and refinement) are

upper jbl

klipsch

tekton

better zu's

atc's (properly driven - no mean feat)

tannoy/fyne

fleetwood/oma

as others have mentioned, subs may well be needed to complete the package for that kind of sound

Bose 901’s!! All of their marketing was that the reflected stereo everywhere was base on their live music delivery research?😂

As I reflect on it. my old Bose 901s sucked!

Acoustic Research AR-9'S WILL ROCK WITH LIVE MUSIC

Magnepan Speakers are unreal for live music. Live music is what I primarily listen to on my 1.7i’s because the soundstage is so vivid and all the nuances of the vocal inflections and crowd interaction are really brought out and bring to make it an immersive experience. 3.7i's are in your price range and are phenomenal.
