Short answer: the ADAM Audio A4V. It ranks #67 of 108 powered bookshelf speakers by sound quality, rated 3.6/5, at $1,079.98. The Audioengine HD6 ranks #79, rated 3.3/5, at $1,048, $31.98 cheaper, not enough of a saving to outweigh the sound-quality gap.
The ADAM Audio A4V is the better-sounding choice. Compact monitor with onboard DSP, placement controls and room-correction integration. 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 case for the Audioengine HD6: Analog and optical inputs, RCA output and built-in amplification provide a convenient self-contained stereo setup. It keeps a wired aux input, which the ADAM Audio A4V lacks. The tradeoff: 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 is rated higher for sound quality, and the $31.98 saving on the Audioengine HD6 is not enough to make up the difference.

Older model: the ADAM Audio A5X (ranked higher, rated 3.7/5). See every ADAM Audio A Series generation.
Same family: the ADAM Audio A44H (larger bookshelf, ranked higher, estimated 3.8/5), the ADAM Audio A7V (larger bookshelf, rated 4/5), the ADAM Audio A8H (larger bookshelf, estimated 4.4/5) and the ADAM Audio A77H (larger bookshelf, estimated 4.4/5).
Pros: 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 3.92 standalone and 6.33 with an ideal subwoofer. Its adjustment facilities are useful when placement or tonal correction is needed.
Cons: 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.

Same family: the Audioengine HD3 (smaller bookshelf, rated 3.2/5), the Audioengine HD4 (smaller bookshelf, ranked lower, rated 3.2/5) and the Audioengine HD5 (larger bookshelf, ranked lower, estimated 3.2/5).
Pros: 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.
Cons: Listening impressions describe bass and treble emphasis with a recessed midrange, which may suit casual listening better than neutral monitoring.
