Short answer: the Audioengine A5+ Classic. It ranks #36 of 100 powered bookshelf speakers by sound quality, rated 4.0/5, at $399; the Vanatoo Transparent Zero Plus ranks #45, rated 3.9/5, and costs $499.99, which makes this an easy call rather than a real tradeoff.
What the Vanatoo Transparent Zero Plus does well: 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.
The Audioengine A5+ Classic is the more accurate, deeper-bass option. ASR’s A5+ Powered measurements give 4.59 standalone and 7.06 with an ideal subwoofer, with a 2.7dB midrange span. Its measured preference score, a predictor of how neutral it sounds, is 4.59 against 4.07 for the Vanatoo Transparent Zero Plus. Its bass reaches about 68Hz before falling 3dB, against 92Hz for the Vanatoo Transparent Zero Plus. Watch for: The measured -3dB point is around 69Hz, and the upper-bass recession can reduce body in voices and instruments.
Buy the Audioengine A5+ Classic. It is rated higher for sound quality than the Vanatoo Transparent Zero Plus and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Speakers In Full
Vanatoo Transparent Zero Plus: $499.99 per pair Amazon eBay
Older model: the Vanatoo Transparent Zero (ranked lower, rated 3.7/5).
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.

Audioengine A5+ Classic: $399.00 per pair Amazon B&H Photo Video eBay
Same family: the Audioengine A2+ (smaller bookshelf, rated 3.4/5).
Pros: ASR’s A5+ Powered measurements give 4.59 standalone and 7.06 with an ideal subwoofer, with a 2.7dB midrange span. The analog powered pair is straightforward to use without an external amplifier. The measured result supports a more capable tonal balance than its former low position suggested. Measured bass extension of 68Hz (-3dB).
Cons: The measured -3dB point is around 69Hz, and the upper-bass recession can reduce body in voices and instruments. The existing review reports crossover-region directivity errors and a distortion feature around 800-900Hz. The score does not make it a reference monitor, and adding a subwoofer cannot correct those midrange and off-axis issues.
