Short answer: the Adam Audio A4V. It ranks #42 of 65 powered bookshelf speakers by sound quality at $599.99; the Audioengine HD6 ranks #51 and costs $817.44, which makes this an easy call rather than a real tradeoff.
What the Adam Audio A4V offers: Compact monitor with onboard DSP, placement controls and room-correction integration. ASR’s Klippel data gives a -3dB point around 59Hz and preference scores of 3.02 standalone and 5.43 with an ideal subwoofer. Its adjustment facilities are useful when placement or tonal correction is needed. Watch for: A small average-deviation figure hides a major localized response irregularity: the selected measurement spans 10.8dB from 300Hz to 5kHz, and listening-window narrow-band deviation is 0.547. The native response should therefore not be called smoothly neutral. Correction potential is not the same as stock performance, and analog audio inputs mean a separate interface is needed for USB sources.
What the Audioengine HD6 offers: Analog and optical inputs, RCA output and built-in amplification provide a convenient self-contained stereo setup. The cabinet and driver size can be practical for general music listening without assembling a separate amplifier system. Watch for: Listening impressions describe bass and treble emphasis with a recessed midrange, which may suit casual listening better than neutral monitoring.
Buy the Adam Audio A4V. It ranks higher for sound quality than the Audioengine HD6 and costs less, which settles it without a real tradeoff to make.
The Audioengine HD6 is not a sound-quality pick. It sits near the bottom of the 65 powered bookshelf speakers; there are better options higher up.
