Short answer: the Audioengine A5+ Classic. Both are rated 4.0/5 for sound quality (#36 and #34 of 100 powered bookshelf speakers), and the Audioengine A5+ Classic costs $399 against $999.99 for the Airpulse A100, so with nothing between them on sound quality, price settles it.
Why pick the Audioengine A5+ Classic: ASR’s A5+ Powered measurements give 4.59 standalone and 7.06 with an ideal subwoofer, with a 2.7dB midrange span. Watch for: The measured -3dB point is around 69Hz, and the upper-bass recession can reduce body in voices and instruments.
The case for the Airpulse A100: ASR’s Klippel data gives a 2.9dB midrange span and scores of 4.56 standalone and 7.08 with an ideal subwoofer. It has an adjustable EQ, which the Audioengine A5+ Classic lacks. The catch: Bass reaches -3dB around 63Hz, so lower notes need a subwoofer for full weight.
Buy the Audioengine A5+ Classic. Both are rated the same for sound quality, and it costs $600.99 less than the Airpulse A100.

The Two Speakers In Full
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.

Airpulse A100: $999.99 per pair Amazon B&H Photo Video eBay
Same family: the Airpulse A60 (smaller bookshelf, estimated 3.8/5), the Airpulse A80 (smaller bookshelf, ranked lower, estimated 3.9/5) and the Airpulse A200T (larger bookshelf, ranked lower, estimated 4/5).
Pros: ASR’s Klippel data gives a 2.9dB midrange span and scores of 4.56 standalone and 7.08 with an ideal subwoofer. The ribbon tweeter and five-inch woofer provide a distinctive compact powered system, with remote control and a subwoofer output simplifying everyday use. Measured bass extension of 63.0Hz (-3dB).
Cons: Bass reaches -3dB around 63Hz, so lower notes need a subwoofer for full weight. Listening-window narrow-band deviation of 0.419 shows more local tonal variation than the leading monitors. Rear tone controls are less flexible than parametric EQ or room correction. Neither the ribbon tweeter nor a directivity-index summary establishes uniquely wide or perfectly controlled dispersion. The remote cannot reach the rear bass and treble knobs, and there is no app EQ.
