Short answer: the Dynaudio LYD 5. It ranks #6 of 105 powered bookshelf speakers by sound quality, rated 4.5/5, at $998. The Audioengine HD4 ranks #86, rated 3.2/5, at $429, $569 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Dynaudio LYD 5 is the better-sounding pick. ASR’s Klippel data is substantially stronger than a low ranking suggests: 4.72 standalone and 7.38 with an ideal subwoofer, with a 1.9dB span from 300Hz to 5kHz. The catch: Bass reaches -3dB around 72Hz, so it gives up low-frequency weight to deeper-reaching monitors.
The case for the Audioengine HD4: Compact powered cabinets, analog input options and RCA output can simplify a desktop stereo system. It keeps a wired aux input, which the Dynaudio LYD 5 lacks. The tradeoff: The compact cabinets suit close desktop listening rather than a large-room system.
Buy the Dynaudio LYD 5. It is rated higher for sound quality, and saving $569 with the Audioengine HD4 does not make up for the sound-quality gap.

Pros: ASR’s Klippel data is substantially stronger than a low ranking suggests: 4.72 standalone and 7.38 with an ideal subwoofer, with a 1.9dB span from 300Hz to 5kHz. Low listening-window narrow-band deviation of 0.242 supports relatively uncolored midrange reproduction. It is particularly competitive when used with a subwoofer rather than judged only by bass reach. Measured bass extension of 68Hz (-3dB).
Cons: Bass reaches -3dB around 72Hz, so it gives up low-frequency weight to deeper-reaching monitors. The existing review identifies a dip near 1.6kHz, upper-bass emphasis and uneven crossover-region dispersion. These issues and limited deep-bass capability keep it below the leading all-rounders despite its strong bass-normalized score. A subwoofer does not correct upper-frequency directivity errors.

Audioengine HD4: $429.00 per pair Amazon eBay
Same family: the Audioengine HD3 (smaller bookshelf, rated 3.2/5), the Audioengine HD6 (larger bookshelf, ranked higher, rated 3.3/5) and the Audioengine HD5 (larger bookshelf, ranked lower, estimated 3.2/5).
Pros: Compact powered cabinets, analog input options and RCA output can simplify a desktop stereo system. Its modest footprint is useful where larger studio monitors are impractical.
Cons: The compact cabinets suit close desktop listening rather than a large-room system. A separate subwoofer adds cost and space if deeper bass is a priority.
