Short answer: the Vanatoo Transparent One Encore Plus. It ranks #15 of 64 powered bookshelf speakers by sound quality at $699.99; the Audioengine HD6 ranks #50 and costs $817.44, so there is not much of a tradeoff to weigh.
What the Audioengine HD6 offers: Its documented strengths make it a credible option in this class. Watch for: A bit of an accentuated treble and bass.
What the Vanatoo Transparent One Encore Plus offers: Smooth, relatively flat on-axis response instead of the pronounced mid-bass-and-treble “V curve” common in this size class, which tends to cause listener fatigue over long sessions. Watch for: A slight sibilance/edge in the 4-6 kHz lower-treble region stood out to the reviewer as mildly fatiguing, though a single band of parametric EQ (about -2dB) fixed it; toeing the speakers off-axis reduces but doesn’t eliminate it.
Buy the Vanatoo Transparent One Encore Plus. It ranks higher for sound quality than the Audioengine HD6 and costs less, so the other one has nothing left to offer.
The Audioengine HD6 is not a sound-quality pick. It sits near the bottom of the 64 powered bookshelf speakers; there are better options higher up.

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.

Vanatoo Transparent One Encore Plus: $699.99 Amazon eBay
Pros: Erin’s Klippel data combines a small 1.7dB midrange response span with a -3dB point around 44Hz. Scores of 4.68 standalone and 6.49 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.
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.
