Short answer: the Devialet Phantom Ultimate 98dB for better sound quality, the Edifier S1000MKII for the lower price. The Devialet Phantom II 98 dB ranks higher than the Edifier S1000MKII (#11 vs #82 of 108 powered bookshelf speakers) but is discontinued. Its replacement, the Devialet Phantom Ultimate 98dB, is rated 4.4/5 at $3,998; the Edifier S1000MKII is rated 3.3/5 at $399.99, $3,598.01 cheaper.
The case for the Edifier S1000MKII: A self-powered stereo pair with optical, coaxial, analog and Bluetooth inputs that makes switching sources simple. It supports aptX HD Bluetooth, which the Devialet Phantom II 98 dB lacks. 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.
The Devialet Phantom II 98 dB is the better-sounding pick. A compact wireless streaming speaker with startlingly deep bass for its size and an even, well balanced sound. Watch for: Small-enclosure bass extension at the measurement level does not guarantee the same response at high volume.
Buy the Edifier S1000MKII if price matters most. For better sound quality, the Devialet Phantom Ultimate 98dB, the replacement for the discontinued Devialet Phantom II 98 dB, is rated higher but costs $3,998.
