Short answer: the KEF Reference 1 Meta. It ranks #3 of 222 bookshelf speakers by sound quality, rated 4.8/5, at $9,999.98. The Dynaudio Special Forty ranks #148, rated 3.5/5, at $3,600, $6,399.98 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the Dynaudio Special Forty does well: Premium bookshelf speakers with strong output, wide dispersion and fairly deep bass from a compact rear ported cabinet. The tradeoff: A glaring, sometimes sibilant quality around 3-4kHz was the most noticeable issue in listening, the one thing the reviewer would want notched out with EQ.
The KEF Reference 1 Meta is the more accurate option. 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 4.73 for the Dynaudio Special Forty. The catch: At roughly $10000/pair, nearly four times the cost of the similarly-sized KEF R3.
Buy the KEF Reference 1 Meta. It is rated higher for sound quality, and the $6,399.98 you would save on the Dynaudio Special Forty does not close the gap.
