Short answer: the Audio First Cadentia 3 for accuracy, the Dynaudio Heritage Special for a very different kind of speaker. The Cadentia 3 ranks #8 of 131 large bookshelf speakers against the Heritage Special’s #28, 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.

The Two Speakers In Full
Audio First Cadentia 3: $7199 Audio First Designs eBay
Pros: Near-textbook measurements - excellent on-axis linearity, listening window, and directivity, with only minor deviations. Extremely low distortion and compression, holding steady even at 102dB with barely any loss. Very wide, consistent horizontal dispersion (~70 degrees) gives a big, enveloping soundstage with strong image specificity outside the speaker boundaries. Strong bass extension for a bookshelf (F3 43Hz, F10 26Hz) with a punchy, guttural mid-bass.
Cons: A mild scoop through the upper midrange/lower treble slightly softens the attack of snares, hand claps, and sibilants - fixable with a single-band EQ (2.5kHz, +1dB, Q~1). High-frequency dispersion narrows quickly above about 4kHz, so off-axis listeners lose some air and detail. Very high asking price for a bookshelf-class speaker, and the complete (finished) version has a long lead time; the loaner kit version ships as an unfinished cabinet you assemble and finish yourself.

Dynaudio Heritage Special: $7,000 Safe and Sound HQ eBay
Pros: One of the rare cases where the reviewer measured a speaker as flawed but still genuinely enjoyed listening to it. A massive 4” voice coil on the midwoofer gives it exceptional output capability for a bookshelf speaker - averaged 100dB at 3.5 meters with no audible mechanical noise, port chuffing, or woofer bottoming even when deliberately pushed hard. Bass is very robust and doesn’t noticeably give up output as volume increases, staying solid at both low and high listening levels. Big, well-proportioned soundstage - wide without losing image focus. Limited run of 2,500 pairs with genuine collectible/heritage value; the tweeter (Esotar 3) and midwoofer both use premium Dynaudio-made drivers with an unusually wide, stout voice coil.
Cons: At lower listening volumes, dynamic range and kick-drum punch fell short of higher-sensitivity speakers the reviewer has tested (JBL 4367, KEF Reference 1 Meta) - the sheer output ceiling is impressive, but it isn’t a highly dynamic-sounding speaker at modest levels. A degree of “softness” in the upper mid-range. Selective sibilance in the 4-6kHz treble region that shows up on some tracks but not others, which the reviewer found mildly aggravating and would want to EQ down given the choice. Neither the tweeter nor the woofer is fully flush-mounted to the baffle, likely intentional as part of the heritage-styled look, but the reviewer wonders how much this affected linearity. At $7,000/pair MSRP (and a discontinued limited run, so used/open-box pricing around $5,000/pair is about the best you’ll do now), this is a serious investment for a bookshelf speaker.
