Short answer: the Devialet Phantom II 98 dB for better sound quality, the Edifier S1000MKII for the lower price. The Devialet Phantom II 98 dB ranks #9 of 65 powered bookshelf speakers at $2998. The Edifier S1000MKII ranks #54 at $399.99, $2598.01 cheaper.
What the Edifier S1000MKII offers: A self-powered stereo pair with optical, coaxial and analog inputs, plus high-resolution digital support, makes source switching unusually simple. Consumer Reports rates its sound accurate and detailed, so it is a strong one-box alternative to separate amplifier-and-speaker systems for nearfield or small-room listening. Watch for: High-resolution input support is not a guarantee of perfect tuning, and the fixed internal amplification prevents the gradual upgrades possible with separates. These are mains-powered speakers rather than portable wireless speakers, and their size and left/right cabling need a planned desktop or stand setup.
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.
Buy the Edifier S1000MKII if the price is the priority over sound quality, or the Devialet Phantom II 98 dB if sound quality is the priority over the price.
The Edifier S1000MKII is not a sound-quality pick. It sits near the bottom of the 65 powered bookshelf speakers; there are better options higher up.
