Short answer: the Radiant Acoustics Clarity 6.2. It ranks #28 of 222 bookshelf speakers by sound quality, rated 4.4/5, at $4,500; the Dynaudio Contour 20i ranks #96, rated 3.9/5, and costs $5,750, so there is not much of a tradeoff to weigh.
The Radiant Acoustics Clarity 6.2 is the better-sounding choice. A Purifi driver bookshelf speaker with an AMT tweeter, rigid cabinet, non-fatiguing sound, and precise, well focused imaging. The catch: 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.
Why pick the Dynaudio Contour 20i: Beautifully built bookshelf speakers with wide, spacious sound, clean output at high volume, and bass that blends easily near a wall. Watch for: Notably room-dependent: sounds too bright in the lower treble in smaller rooms with close sidewalls, needing sidewall absorption to sound neutral, while performing better in larger or more open rooms without that treatment.
Buy the Radiant Acoustics Clarity 6.2. It is rated higher for sound quality than the Dynaudio Contour 20i and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
