Short answer: the Vanatoo Transparent Zero Plus. It ranks #35 of 68 powered bookshelf speakers by sound quality, rated 3.9/5, at $499.99; the Audioengine HD6 ranks #54, rated 3.3/5, and costs $817.44, so there is not much of a tradeoff to weigh.
Why pick the Vanatoo Transparent Zero Plus: Erin’s data shows a small 1.7dB span from 300Hz to 5kHz and a broadly level midrange trend. The tradeoff: The measured -3dB point is around 95Hz, with a much lower F10 in the original review; this is not flat bass to the low-50Hz region.
Why pick the Audioengine HD6: Analog and optical inputs, RCA output and built-in amplification provide a convenient self-contained stereo setup. The tradeoff: Listening impressions describe bass and treble emphasis with a recessed midrange, which may suit casual listening better than neutral monitoring.
Buy the Vanatoo Transparent Zero Plus. It is rated higher for sound quality than the Audioengine HD6 and costs less, so only choose the other one for a particular feature it does better.

Vanatoo Transparent Zero Plus: $499.99 per pair Amazon eBay
Pros: Erin’s data shows a small 1.7dB span from 300Hz to 5kHz and a broadly level midrange trend. Scores of 4.07 standalone and 6.73 with an ideal subwoofer support it as a useful compact desktop option. Flexible cabinet orientation, multiple inputs and automatic subwoofer crossover behavior help with setup. Measured bass extension of 92Hz (-3dB), with a measured sensitivity of 88.5dB.
Cons: The measured -3dB point is around 95Hz, with a much lower F10 in the original review; this is not flat bass to the low-50Hz region. Vertical listening angle changes the upper-midrange response. The review finds cleaner results at moderate levels than near maximum output, where multitone distortion increases. A subwoofer is particularly valuable here. An 8th-order high-pass filter at 58Hz sharply cuts bass below that point, so kick drum fundamentals need a subwoofer.

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.
