A speaker that comes to my mind given your criteria is the Legacy Audio Whisper. It's physically imposing, but unlike most speakers that size, its free-air woofers function as dipoles, making it easy to place them closer to side walls. The woofers can also be amped and attenuated separately, so it is relatively easy to dial the speakers in to the room size and avoid bass overload.
Finally, the Whispers are aptly named if the multiple reviews are to be believed. The reviews consistently report that they are particularly good at low level detail and holding the musical presentation together at low volumes.
Stereophile review here.
Also, given your criteria for detail plus engaging musicality, the Sonus Faber Cremona is a must-listen. The SF's all have a very natural-sounding tonal balance, the antithesis of hyped-up "hi-fi."
