Short answer: both are discontinued, so this only matters if you are buying used. Used, the Devialet Phantom II 98 dB is the better pick: it ranks #11 of 108 powered bookshelf speakers by sound quality (rated 4.4/5), against #70 (rated 3.5/5) for the PreSonus Eris E5 XT. If you want one new, the Devialet Phantom Ultimate 98dB replaces the Devialet Phantom II 98 dB and is rated 4.4/5 at $3,998.
The Devialet Phantom II 98 dB is the more accurate, deeper-bass option. A compact wireless streaming speaker with startlingly deep bass for its size and an even, well balanced sound. Its measured preference score, a predictor of how neutral it sounds, is 6.87 against 3.58 for the PreSonus Eris E5 XT. Its bass reaches about 30Hz before falling 3dB, against 56.4Hz for the PreSonus Eris E5 XT. Watch for: Small-enclosure bass extension at the measurement level does not guarantee the same response at high volume.
The case for the PreSonus Eris E5 XT: An affordable 5 inch studio monitor with fairly deep bass and balanced XLR, TRS and RCA inputs. The tradeoff: The response has bass and treble emphasis with a recessed crossover region; smooth directivity carries that imbalance into room reflections rather than fixing it.
Buy the Devialet Phantom II 98 dB only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Devialet Phantom Ultimate 98dB, which replaces the Devialet Phantom II 98 dB.
