Short answer: the KEF Reference 1 Meta on measured sound quality, the Buchardt Audio E50 on price. The KEF Reference 1 Meta ranks #3 of 222 bookshelf speakers, rated 4.8/5, at $9,999.98. The Buchardt Audio E50 ranks #16, rated 4.5/5, at $4,600, $5,399.98 cheaper.
The KEF Reference 1 Meta is the more accurate choice. Extremely accurate bookshelf speakers, with a superb three dimensional soundstage, no harshness, and tightly matched pairs. Its measured preference score, a predictor of how neutral it sounds, is 6.48 against 5.84 for the Buchardt Audio E50. Watch for: At roughly $10000/pair, nearly four times the cost of the similarly-sized KEF R3.
The Buchardt Audio E50 is the deeper-bass pick. A bookshelf speaker with remarkably deep bass for its size, a very neutral midrange, and low distortion, with no need to sit near a wall. Its bass reaches about 40Hz before falling 3dB, against 52Hz for the KEF Reference 1 Meta. The tradeoff: A roughly 3dB dip in the upper midrange/lower treble softens attack and dialogue clarity: the reviewer’s main complaint, and it’s baked into the crossover rather than a directivity artifact, so it’s audible both on and off axis.
Buy the KEF Reference 1 Meta when sound quality outweighs the price for you, and the Buchardt Audio E50 when the price outweighs sound quality instead.

- Close enough not to matter: bass extension (32 Hz vs 34 Hz, 10 dB down).
