Short answer: the Kanto YU4. It ranks #14 of 24 powered bookshelf speakers by sound quality, rated 3.3/5, at $479.99. The Audioengine HD3 ranks #17, rated 3.2/5, at $359, $120.99 cheaper, which does not close the gap in sound quality.
The case for the Kanto YU4: Phono, optical and Bluetooth inputs, remote control and a subwoofer output make it convenient for a compact multi-source system. Watch for: Standalone preference is only 2.89, with a -3dB point around 86Hz and a 4.2dB midrange response span.
What the Audioengine HD3 does well: A compact desktop stereo option when cabinet size is a priority. The tradeoff: Limited bass makes a subwoofer useful for fuller music reproduction.
Buy the Kanto YU4. It is rated higher for sound quality, and saving $120.99 with the Audioengine HD3 does not make up for the sound-quality gap.

The Two Speakers In Full
Kanto YU4: $479.99 per pair Kanto eBay
Pros: Phono, optical and Bluetooth inputs, remote control and a subwoofer output make it convenient for a compact multi-source system. ASR’s measured horizontal coverage is broad enough for some freedom of seating position. The ideal-subwoofer preference score of 5.83 indicates that bass support would materially improve its usefulness.
Cons: Standalone preference is only 2.89, with a -3dB point around 86Hz and a 4.2dB midrange response span. Response irregularities remain even after bass extension is removed from the comparison, so a subwoofer alone will not make it neutral. Sensitivity measured at an arbitrary powered-speaker gain setting is not a reliable basis for judging efficiency or maximum volume.
