Short answer: the Vanatoo Transparent One Encore Plus. It ranks #20 of 108 powered bookshelf speakers by sound quality, rated 4.3/5, at $699.99; the Audioengine HD6 ranks #79, rated 3.3/5, and costs $1,048, so there is not much of a tradeoff to weigh.
What the Audioengine HD6 does well: A self-contained powered stereo pair with Bluetooth, analog and optical inputs, and an RCA output, no separate amplifier needed. It keeps a wired aux input, which the Vanatoo Transparent One Encore Plus lacks. Watch for: Listening impressions describe bass and treble emphasis with a recessed midrange, which may suit casual listening better than neutral monitoring.
The Vanatoo Transparent One Encore Plus is the better-sounding option. Powered speakers with natural, even sound and deep bass for their size, plus lots of digital inputs and a subwoofer output. The tradeoff: 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.
Buy the Vanatoo Transparent One Encore Plus. It is rated higher for sound quality than the Audioengine HD6 and costs less, which makes it the one to get unless you need something the other one does better.
