Short answer: the Radiant Acoustics Clarity 6.2. Both are rated 4.4/5 for sound quality (#28 and #29 of 222 bookshelf speakers), and the Radiant Acoustics Clarity 6.2 costs $4,500 against $7,000 for the Dynaudio Heritage Special, so with nothing between them on sound quality, price settles it.
The Radiant Acoustics Clarity 6.2 is the more accurate pick. A Purifi driver bookshelf speaker with an AMT tweeter, rigid cabinet, non-fatiguing sound, and precise, well focused imaging. Its measured preference score, a predictor of how neutral it sounds, is 5.97 against 4.32 for the Dynaudio Heritage Special. Watch for: Needs a fairly specific setup to sound its best: about 15-20° of toe-out (per the manufacturer’s own recommendation) and roughly 2 feet from the rear wall; pointed straight on-axis, the treble reads as noticeably elevated.
The case for the Dynaudio Heritage Special: A limited edition bookshelf speaker with huge output for its size, robust bass, and a big, well proportioned soundstage. The tradeoff: 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.
Buy the Radiant Acoustics Clarity 6.2. Both are rated the same for sound quality, and it costs $2,500 less than the Dynaudio Heritage Special.
