Short answer: the Dynaudio Contour 20i on measured sound quality, the SVS Prime Bookshelf on price. The Dynaudio Contour 20i ranks #96 of 222 bookshelf speakers, rated 3.9/5, at $5,750. The SVS Prime Bookshelf ranks #150, rated 3.5/5, at $599, $5,151 cheaper.
What the SVS Prime Bookshelf does well: Affordable bookshelf speakers with a sealed woofer compartment, wide even dispersion and reasonable sensitivity. The catch: A scooped mid-range paired with a boosted upper mid-range creates an audibly uneven tonal balance, and there’s an additional dip in the treble around 4-5kHz that reads as slightly tinny relative to the recessed mid-range.
The Dynaudio Contour 20i is the better-sounding, deeper-bass choice. Beautifully built bookshelf speakers with wide, spacious sound, clean output at high volume, and bass that blends easily near a wall. Its bass reaches about 56Hz before falling 3dB, against 72Hz for the SVS Prime Bookshelf. 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 SVS Prime Bookshelf when the price outweighs sound quality for you, and the Dynaudio Contour 20i when sound quality outweighs the price instead.
