@ArthurM we got a bunch of people here asking what DAC this thing uses and no response, I'm not going to even consider buying this without knowing what DAC is inside.
P.S. sorry to tag you in particular since I know your logistics but I don't know who to tag that would know the answer so maybe you can find out for us?

SurfinsamIt's almost certainly some $0.02 chip, and it's on the 'WiiMu' module, which appears to be a knockoff of another companies chip. You should be able to find the chip and a PDF from the FCC with some google.
Plain and simple, it's not a device for audiophiles. There's no point even asking about the internals. It is a device for folks that are perfectly happy with the sound chip in their phone, or laptop, but want something that looks cool. There's no reason for this unit to even be in two pieces, and it is probably split like this to makes it look "more audiophile".
Not sure about their tube choice either...

Caveat - Never seen one of these or even heard of such before this drop. The comments are conjectures based on the available photos, vendor ads, app reviews and app manual PDF.
Apparently you need an app, MUZO Cobblestone to control the Wi-Fi. But reviews currently place this app somewhere south of usable. There are broken features being reported.
It looks like you need a phone (Wi-Fi) or a PC (USB). Music files can be sourced from the internet (Wi-Fi), a thumb drive (USB), an SD card, or the PC. Not sure if you can use a USB hard drive instead of thumb drive, but I would think so. The phone can then be disconnected once the software is configured.
You can have several Cobblestone-enabled devices around the area without physical connections using the Wi-Fi. The Wi-Fi will also act a repeater to enlarge the coverage area. Bluetooth has shorter range and can only connect to one device at a time.

I'm really disappointed in Massdrop for selling this shoddy thing. Don't they have any standards?

Shame it doesn't invoke my confidence, I could use something like this in my workshop. I'm thinking that at $175, it's probably more about making it "look" high-end, and less about actual performance. If it looks too good to be true...
