Verdict

Which should you buy?

The Elac Debut B5.2 is my pick here. It has the stronger sound quality and far more convincing bass of the two, and it delivers that at better value, which leaves the Dynaudio Emit M20 as the more specialised choice.

Buy the Dynaudio Emit M20 if your listening leans on detail rather than weight. It has the finer treble of the pair, narrowly, and the staging and dynamic range it pulls out of jazz, acoustic and ambient material are the reason to choose it. It also edges the design question by a small margin, with craftsmanship that holds up and a plain look that sits quietly in most rooms. Two conditions apply: it wants a capable amplifier, since the 4 Ω load and 86 dB sensitivity punish a weak one, and it wants either a room that flatters the low end or a subwoofer, because bass is where it gives ground. The two year warranty is the shorter of the two.

Everyone else should take the Elac Debut B5.2. It is the stronger performer on sound quality and it holds a wide lead on bass, producing tight, natural low end from a compact speaker with no subwoofer needed for most music, which makes it the easier one to place on a desk or in a small room. The 6 Ω load and the 30 to 120 W recommendation suit modest integrated amps and receivers, the sparkle at the top end settles with a treble control if it bothers you, and the three year warranty is longer. On value it is the clear winner, and it is the pair I would live with.
