I've had a new Wavelight for a few days, though I'm also waiting for new speakers to arrive, so can't speak to sonics much yet. Just a couple functional points to add.
While it can be used as a preamp with its analog volume control, there is no physical remote planned and, at this time, just an Android app available to control it via Bluetooth (IOS is "coming"). My experience with the app on a FireHD is it refreshes whenever the control device sleeps or goes into screen save, sometimes it just hangs and loses connection, needing an app or device restart, very annoying. Using it as primary volume/mute in your system, as you would with any preamp, is rather dodge imho. For these guys, who are clearly quite sophisticated, a $30 Apple remote integration would be trivial to do since BT functionality is already there.
The other issue is there is no Roon integration at all, meaning Roon cannot control any of the DAC's features, but especially that nice analog volume control. The DAC appears as a generic ALSA device to my Innuos streamer via USB when using Roon. If Roon's app could control at least volume/mute then the Android app would be a non-issue for those users. I assume this would apply to any Linux based streamer.
Also, DSD seems to be limited to DSD128, though they told me they're working on a solution to enhance DSD for Linux. The spec sheet does in fact say DSD64-512, but does not mention it doesn't do it on Linux (yet).
