I like classical music too when I’m working at my desk.
but positioning large speakers behind you as a choice to simply “ go big” , appears to be a force-fit option IMO that is anything BUT optimal. IMO it’s like putting a square peg in a round hole, with significant damage to the peg.
Classical music has never been presented live nor recorded when delivered from a soundstage that is 180 degrees BEHIND YOU that is out of whack with a live stage or orchestra pit performance otherwise in front of you . Without prejudice to the obvious perversion, the “live performance” reverb and reflections normally pleasantly and subtly behind you that fill out the experience are now in front of you ?? Think a bit weird, n’est pas? Think Wagner - RIDE OF THE VALKYRIES or The Planets, Op.32 (Holst, Gustav) in reverse .
Maybe pop music delivered from behind you might be okay as a comparatively mindless elevator music ditty …ok …. Fine .,,, carry on, I guess ….Just not classical or other fine 2-channel recordings.
TAKEAWAY….. a proper “ normal” 3D soundstage delivered from in front of you is the real deal , actually the only option IMO. ERGO…. Think nearfield listening standmounts options,
FWIW.
