Short answer: the Devialet Phantom Ultimate 98dB for better sound quality, the Edifier R1700BT for the lower price. The Devialet Phantom II 98 dB ranks higher than the Edifier R1700BT (#11 vs #88 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 R1700BT is rated 3.2/5 at $219.99, $3,778.01 cheaper.
The case for the Edifier R1700BT: A compact powered pair with Bluetooth and analog inputs for easy desktop listening without a separate amplifier. The catch: Listening impressions suggest a bass-and-treble-forward balance rather than strict neutrality.
The Devialet Phantom II 98 dB is the better-sounding choice. A compact wireless streaming speaker with startlingly deep bass for its size and an even, well balanced sound. The tradeoff: Small-enclosure bass extension at the measurement level does not guarantee the same response at high volume.
Buy the Edifier R1700BT 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.
