Short answer: the KEF Q Concerto Meta. It ranks #11 of 222 bookshelf speakers by sound quality (rated 4.6/5); the Epos ES14N ranks #19 (rated 4.5/5).
The case for the KEF Q Concerto Meta: A neutral three way bookshelf speaker that sounds consistent from seat to seat, with smooth treble that many rivals at its price lack. Watch for: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
The case for the Epos ES14N: A modern revival of a classic British bookshelf speaker with a time aligned sloping baffle, smooth accurate sound, and very low distortion. Watch for: Off axis sound tracks the on axis response less consistently than most measured speakers as frequency rises, so the room’s reflected sound differs more from what you hear directly.
