Short answer: the Arendal 1528 Monitor 8. It ranks #22 of 130 bookshelf speakers by sound quality at $6000; the Dynaudio Heritage Special ranks #28 and costs $7000, so there is little reason to consider the other one.
What the Arendal 1528 Monitor 8 offers: Three-way design featuring a 28mm tweeter, 5” mid-range, and dual 8” mid-bass drivers in a convertible sealed/ported HDF cabinet, with a supplied port bung for sealed operation near a wall. Watch for: A dip in the midbase around 100Hz noticeably reduces the “chestiness” of male vocals compared to the reviewer’s reference speaker.
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…

Arendal 1528 Monitor 8: $6000 per pair Arendalsound eBay
Pros: Three-way design featuring a 28mm tweeter, 5” mid-range, and dual 8” mid-bass drivers in a convertible sealed/ported HDF cabinet, with a supplied port bung for sealed operation near a wall. In ported configuration, reaches down to about 35Hz in most rooms (F3 41Hz, F10 26Hz) - deep enough that many listeners could skip a subwoofer unless they want output below 40Hz. Extremely low distortion and compression across the board (harmonic, multitone, and both long- and short-term compression testing) - among the best the reviewer has tested at this price, beating speakers costing twice as much. Wide, consistent horizontal soundstage of about ±60°. Smooth, non-fatiguing high frequency rather than the elevated “detail” boost common on speakers marketed for resolution. A slight forwardness around 1.5kHz adds a touch of attack without tipping into brightness. Measured bass extension of 41Hz (-3dB), with a measured sensitivity of 84.4dB.
Cons: A dip in the midbase around 100Hz noticeably reduces the “chestiness” of male vocals compared to the reviewer’s reference speaker. A diffraction-related flare in the upper-midrange/lower-treble (around 1.5-2kHz) gives a mild forwardness that benefits from sidewall absorption panels, though it’s not a major issue. Vertical sweet spot is fairly narrow at about ±20° - a bigger consideration for multi-row home theater seating than rivals like the MoFi SourcePoint 8, which manages about ±60°. The MoFi SourcePoint 8, a similarly-priced rival, also has more linear bass with no midbase dip, at the cost of a more elevated top end. Minor resonances appear around 400Hz and 800Hz in measurements, though the reviewer considers them inaudible or insignificant. Very heavy (about 104 lbs each) HDF cabinet requires dedicated, sturdy stands. Low EPDR (dips to about 1.9 ohms in two spots) means a Class AB amplifier needs to comfortably handle a 4-ohm load without overheating; a Class D amp is a safer choice for full-range use.

Dynaudio Heritage Special: $7,000 per pair 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. Measured bass extension of 52Hz (-3dB), with a measured sensitivity of 85dB.
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.
