Short answer: the Adam Audio T5V. It ranks #12 of 58 powered bookshelf speakers by sound quality at $239.99; the Audioengine HD4 ranks #52 and costs $429, so there is not much of a tradeoff to weigh.
What the Adam Audio T5V offers: Better than the HS5 in terms of vocals detail and better low end. Watch for: Elevated, slightly uneven top end from the AMT tweeter, shared with Adam’s other T-series monitors - the rear treble trim only tilts the response rather than flattening it. Distortion, while better controlled than most speakers in this price range, isn’t reference quality.
What the Audioengine HD4 offers: Watch for: Not a great sounding speaker for the high price.
Buy the Adam Audio T5V. It ranks higher for sound quality than the Audioengine HD4 and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Audioengine HD4. It ranks near the bottom of the 58 powered bookshelf speakers, so look higher up the list instead.
