Short answer: the Audioengine A5+ Classic. It ranks #36 of 100 powered bookshelf speakers by sound quality, rated 4.0/5, at $399; the Audioengine HD6 ranks #77, rated 3.3/5, and costs $1,048, which makes this an easy call rather than a real tradeoff.
The Audioengine A5+ Classic is the better-sounding pick. 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.
What the Audioengine HD6 does well: Analog and optical inputs, RCA output and built-in amplification provide a convenient self-contained stereo setup. The tradeoff: Listening impressions describe bass and treble emphasis with a recessed midrange, which may suit casual listening better than neutral monitoring.
Buy the Audioengine A5+ Classic. It is rated higher for sound quality than the Audioengine HD6 and costs less, so only choose the other one for a particular feature it does better.

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.

Audioengine HD6: $1,048.00 per pair Amazon eBay
Same family: the Audioengine HD3 (smaller bookshelf, rated 3.2/5) and the Audioengine HD4 (smaller bookshelf, ranked lower, rated 3.2/5).
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.
