Short answer: the Devialet Phantom II 98 dB for better sound quality, the Yamaha HS5 for the lower price. The Devialet Phantom II 98 dB ranks #10 of 60 powered bookshelf speakers at $2998. The Yamaha HS5 ranks #13 at $339.98, $2658.02 cheaper.
What the Yamaha HS5 offers: Very neutral. Excellent for mixing and anything needing a neutral output. Watch for: Not quite as deep of bass as some of the others in this size class. Slight midrange boost.
What the Devialet Phantom II 98 dB offers: Exceptional bass for its tiny sealed enclosure measures 30Hz at -3dB, 25.8Hz at -6dB, and 22.4Hz at -12dB, with a well-damped 0.302 low-frequency Q. The 2.58 sound-power directivity-index standard deviation indicates broad, consistent dispersion, and preference scores reach 6.07 without a subwoofer and 7.15 with one. Each speaker integrates amplification, Wi-Fi, AirPlay 2, Spotify Connect, Roon, Bluetooth, Ethernet, and optical/analog input. Watch for: The medium-quality manufacturer measurement has a 2.3dB reference band and 0.590dB on-axis average absolute deviation, good rather than class-leading linearity. Stereo requires two individually powered network speakers and costs nearly $3,000; maximum output is rated at 98dB at 1m per speaker, and the all-in-one architecture offers less serviceability and system flexibility than conventional monitors.
Buy the Yamaha HS5 if the price matters more than sound quality. Buy the Devialet Phantom II 98 dB if sound quality matters more than the price.
