Short answer: the Devialet Phantom II 98 dB for better sound quality, the Audioengine HD6 for the lower price. The Devialet Phantom II 98 dB ranks #9 of 65 powered bookshelf speakers at $2998. The Audioengine HD6 ranks #51 at $817.44, $2180.56 cheaper.
What the Devialet Phantom II 98 dB offers: The manufacturer-supplied measurement shows unusually deep bass for the enclosure size: -3dB at 30Hz. Scores of 6.07 standalone and 7.15 with an ideal subwoofer suggest that its appeal is not limited to bass quantity. Integrated amplification and network playback can replace several components, and its 2.3dB midrange response span is reasonably even. Watch for: Small-enclosure bass extension at the measurement level does not guarantee the same response at high volume. Stereo requires two units, and the integrated architecture offers less system flexibility than conventional monitors.
What the Audioengine HD6 offers: 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. Watch for: Listening impressions describe bass and treble emphasis with a recessed midrange, which may suit casual listening better than neutral monitoring.
Buy the Devialet Phantom II 98 dB if sound quality matters more than the price. Buy the Audioengine HD6 if the price matters more than sound quality.
The Audioengine HD6 is not a sound-quality pick. It sits near the bottom of the 65 powered bookshelf speakers; there are better options higher up.
