I've owned a Devialet Phantom speaker for about a year now, and I'm quite impressed with its performance. The sound quality is exceptional across various genres, from classical to rock and electronic; the bass is deep, and the clarity is top-notch even at higher volumes. The setup was straightforward, although the app could be a bit more intuitive. As for durability, my unit has held up well without any issues. I haven't needed to utilise after-sales support yet, so I can't comment on that aspect. Overall, if you're considering it and the price isn't a deterrent, I'd recommend giving it a shot!
