Short answer: the Audio First Cadentia 3 for accuracy, the Dynaudio Heritage Special for a very different kind of speaker. The Cadentia 3 ranks #7 of 222 large bookshelf speakers against the Heritage Special’s #29, and the two were engineered around opposite priorities.
The Cadentia 3 measures about as clean as bookshelf speakers get. Its notes describe near-textbook on-axis linearity, listening window, and directivity, extremely low distortion and compression that holds steady even at 102dB, and wide, consistent horizontal dispersion around 70 degrees for an enveloping soundstage. Bass extension is strong for the class at F3 43Hz and F10 26Hz with punchy mid-bass. Its only real flaw is a mild scoop through the upper midrange and lower treble that softens snares and sibilants, which the reviewer notes is fixable with a single-band EQ.
The Heritage Special trades some of that flatness for scale and dynamics. Its reviewer explicitly calls it a rare case of measuring flawed but still being genuinely enjoyable to listen to. A massive 4” voice coil on the midwoofer gives it exceptional output capability, averaging 100dB at 3.5 meters with no audible mechanical noise or woofer bottoming even pushed hard, and bass output holds steady rather than compressing as volume increases. The tradeoff shows up at lower volumes, where dynamic range and kick-drum punch fall short of higher-sensitivity speakers the reviewer has tested, plus a degree of softness in the upper midrange and selective sibilance in the 4 to 6kHz region.
The Heritage Special is also a limited edition, built as a run of 2,500 pairs with genuine collectible value, while the Cadentia 3 remains in production, albeit with a long lead time on the finished cabinet version.
Buy the Audio First Cadentia 3 if you want the more neutral, textbook-measuring speaker and don’t mind waiting on the finished-cabinet lead time.
Buy the Dynaudio Heritage Special if huge dynamic headroom, heritage-driver pedigree, and collectible scarcity matter more to you than flat on-axis response.

- Tonal accuracy above the bass: with a subwoofer taking the low end, the Audio First Cadentia 3 scores 8.9 against 6.3 for the Dynaudio Heritage Special on the Spinorama preference scale.
