Short answer: the Audio First Cadentia 3 for better sound quality, the Dynaudio Heritage Special for the lower price. The Audio First Cadentia 3 ranks #8 of 84 bookshelf speakers at $7199. The Dynaudio Heritage Special ranks #23 at $7000, $199 cheaper.
What the Audio First Cadentia 3 offers: Near-textbook measurements - excellent on-axis linearity, listening window, and directivity, with only minor deviations. Watch for: 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).
What the Dynaudio Heritage Special offers: One of the rare cases where the reviewer measured a speaker as flawed but still genuinely enjoyed listening to it. Watch for: 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…

The Two Speakers In Full
Audio First Cadentia 3: $7199 Audio First Designs
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
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.
