@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?

It'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...
"Science, betch!!!"
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...
Would this support the Chromecast format?
I think it's like that family guy episode, this contraption deosnt make u breakfast it just shoots you.
When you look back in the history books about why they United States will attack China, it will be for selling junk that looks like this to it's people. Lol at least fool everyone by jacking the price up and say that what you are selling is "groundbreaking". The Audiophile community should change their name block to "Sucker" if this thing goes through.
Do the tubes come pre-tilted?

If you look at the white tube holding plastic, it is also slanted. It's just poorly made.
Agreed, they just need a better tube fluffer for the photo shoot.
Is it April Fool's already?
Can I get a silver one? And plz let me more information about DAC chip.
I like the way it looks like a robot.
More details about the DAC would be nice.
There's valid speculation about the interference, etc, but if it actually works well and sounds good, however, that's what it really comes down to.
So how does it sound? I've owned and heard plenty of tube amps over the years, only a few of them really sounded special.
At this point in my journey, I'm only interested in tube amps that really stand out. Competent or pretty good sounding are already covered on my end.
For the price, I doubt it rises to that level. But it could be a worthwhile product generally if it actually sounds good.
I have this very amp I was lucky enough to get to do a review on it on amazon it sound nice but the instructions are no place to be found so I could not test the wifi out also I could not get it to play any music via the USB or the SD slot I asked the company for advise but never herd a thing from them a real shame its a small unit what looks very nice. you can buy now in the uk for £200 https://www.amazon.co.uk/APPJ-PA1601A-Amplifier-Electrical-Source-Black/dp/B01JIFQXWG/ref=cm_aya_orig_subj
*** I had a email from the company after my review with the instructions you need to have the unit on the wifi settings to play the USB and SD card not sure what they have done that but it does now work and plays my MP3's so it is a lot better. Its only a small unit but it does sound nice on vocal tracks its no good for drum and Base tunes
This would be quite a conversation piece for your desktop audio system! It's the first tube amp with wi-fi that I've ever seen.
Confusing, yes, and the fact that they misspelled RCA twice as "RAC" doesn't lend much confidence either lmao
ohshitgorillas
plus you get no instructions with it so you have to be a Jedi to work the wifi or even the USB or SD card reader I could not get it to work even with a simple MP3
TechChecker
My question is how would the SD card as a source even work? There are no physical controls for selecting a file out of the thousands that may be present on the card. Perhaps a web GUI or some other software? As noted, nothing is stated or seems to be provided.
The more that I look at this thing, the faster I want to run. Too bad, because on the surface it appears to be a useful product.
I must say, I have never seen anything like this before. A question springs to mind right away for me: with the digital input options like USB it obviously must house some kind of DAC. What DAC chip and what what does it support (96kHz, 192kHz... DSD?)???

"Confusing," was the same thing I thought too. It looks to me: The 3-pin is your everyday grounded power cable that plugs into a receptacle on the "Power A," unit. I believe what they have done is shoved the rectifier and a couple power transformers into that unit. The tube unit needs some high voltage DC for the amplifier section, and some regulated low voltage DC for the RF receiver. Hence the weird 5 pin cable. Also, having the transformers in the the separate box will solve the 60 Hz hum that would definitely overwhelm you if this was all in a single chassis. Power A has a 5 pin connection for outputting for your DC signals. The other box has the matching input.
The other thing that confused me was: they went to all this trouble to isolate the power section, but then carelessly shoved the receiver in the amplifier circuit. To me, this smells like a hack mod. Save your money.
The power unit takes "Input AC voltage: 100 – 250 V AC", no frequency stated. My guess is that they are allowing buyers to get whatever line cord is needed for their local mains. US is different from UK, etc. Also, I happen to have a couple of dozen 3-prong line cords in a box from various products that I have purchased over the years. Others may have more or less hanging around.
The device is stated to be a "speaker amplifier", whatever. Another guess is that the writer of the text is attempting to tell us that a headphone jack is not included since most the MD amps presented are "headphone amplifiers".
