Short answer: the Vanatoo Transparent One Encore Plus. It ranks #19 of 100 powered bookshelf speakers by sound quality, rated 4.3/5, at $699.99. The Audioengine HD4 ranks #83, rated 3.2/5, at $429, $270.99 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Vanatoo Transparent One Encore Plus is the better-sounding pick. Erin’s Klippel data combines a small 1.7dB midrange response span with a -3dB point around 44Hz. Watch for: A mild 4-6kHz edge and a smaller 1-2kHz recession were audible in the review, so its smooth midrange summary does not mean there is nothing to improve with EQ.
Why pick 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 Vanatoo Transparent One Encore Plus lacks. Watch for: The compact cabinets suit close desktop listening rather than a large-room system.
Buy the Vanatoo Transparent One Encore Plus. It is rated higher for sound quality, and the $270.99 saving on the Audioengine HD4 is not enough to make up the difference.

Vanatoo Transparent One Encore Plus: $699.99 per pair Amazon eBay
Older model: the Vanatoo Transparent One Encore (ranked lower, rated 3.9/5).
Pros: Erin’s Klippel data combines a small 1.7dB midrange response span with a -3dB point around 44Hz. Scores of 5.57 standalone and 7.38 with an ideal subwoofer make it an attractive standalone system as well as a subwoofer partner. Remote tone controls, multiple digital and analog inputs, and automatic subwoofer crossover engagement simplify setup. Measured bass extension of 42Hz (-3dB).
Cons: A mild 4-6kHz edge and a smaller 1-2kHz recession were audible in the review, so its smooth midrange summary does not mean there is nothing to improve with EQ. No HDMI ARC. Deep bass and louder playback still benefit from a subwoofer; amplifier wattage alone does not establish clean room-filling output.

Audioengine HD4: $429.00 per pair Amazon eBay
Same family: the Audioengine HD3 (smaller bookshelf, rated 3.2/5) and the Audioengine HD6 (larger bookshelf, ranked higher, rated 3.3/5).
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.
