This guy makes a lot of assumptions. He says he understands manufacturing, but I am not so sure... I think the people at Innuos would wan't to respond to this guy.

Like he said, he's "guessing" .   Which means he has NO clue, he;s looking at a picture to make his claims.

Are you sure?

Just look at the article he got the picture from: https://darko.audio/2017/10/richer-sounds-with-the-innuos-zenith-mkii-se/

Here is a nice break down of the innuos power supply which is defiantly really well made

 

http://www.the-ear.net/how-to/power-supply-design-innuos-statement

 

But it's powering a $150 Supermicro motherboard which is covered with small switching power supplies.

You are connecting the DAC directly to the USB output from the board (although I think the more expensive versions have a special USB card). This doesn't seem that good. The noise from the switchers will go down the USB bus.

Here we go again.................. :)

The mark 11 zenith /se etc, used the supermicro X10sba-L the new mark 3 versions have a new board. A quote from their site:

" New Custom Motherboard with reduced EMI ''

Sure it has switching regulators, but some of the noisier ones removed.

For example on the higher end models you have the new USB board with OCXO clock, lower down the USB bus is powered by a linear power supply, I don't have all the details but you can easily inquire with Innuos to get the exact spec. and changes.

Innuos said in the past they tested dozens of motherboards and used the lowest noise ones they found. Said the better off the shelf boards were better than some custom boards.


Main listening (small home office):

Surge protector +_iFi  AC iPurifiers >Isol-8 Mini sub Axis Power Conditioning+Isolation>CAPS IV Pipeline Server + Sonore 12V PS>Kii Control>Audiolense DRC>Kii Three >GIK Room Treatments.
 

Secondary Listening: CAPS Pipeline>IFi iOne DAC>Schiit Freya>Kii Three . Also an SBT and a RB Pi 3B+ running piCorePlayer as an SBT emulator. 

All absolute statements about audio are false :)

Here is the new board inside the Statement with OCXO clock board. I think the CPU is also slightly bigger than Mk 2 models.

Do you know whether this is another SuperMicro board?  Do you know the model number?  I think Innuos said the motherboard in the Statement is custom, but I don't know what they customized.


NUC7PJYH/AL --> Berkeley Alpha USB --> Jeff Rowland Aeris --> Jeff Rowland 625 S2 --> Focal Utopia 3 Diablos with 2 x Focal Electra SW 1000 BE subs

 

i7-6700K/Windows 10 Version 1903/HDPLEX 200W/HDPLEX 400W DC-ATX --> EVGA Nu Audio Card --> Focal CMS50's

I think its a Supermicro board, I don't know the model no/ the nearest board.....yet :)- if I did it would be in my server

 

Here is a snapshot of the motherboard of the mark 3 without OCXO boards taken from Darko's youtube review/ video:

I can see (it looks like) a power connector going direct to the USB/ ethernet outputs - replacing the switching regulators with linear power, from the SJ supply.

The MKIIIs use the Intel N4200 stated in their product specifications.

http://www.innuos.com/en/catalog/go/zenith-mk3-1tb-ssd-black

I think the Supermicro board they modify is the X11SAA that use the N4200. Very similar to the ATOM MB.

I thought the same at first too. But I believe this is just a USB cable for a USB to LED controller. Zoom in the picture below. There is function to change the front LED light color.

The USB DAC and Ethernet outputs are on the motherboard, at the back of the unit. 

 

Let me clarify... 

I assumed LTG2010 was referring to the green/yellow/red/black cable on the picture he posted that goes from the USB header on the motherboard towards the power supply.

If that's the case, I don't think this is a "power connector going direct to the USB/ ethernet outputs". It seems to me like this is a USB cable for the USB LED Controller that can be seen on the picture I posted.

Yes you are correct, after I identified the board I checked the motherboard manual. It's just a usb header. And that's where the connection to the USB ocxo clock is taken for the Statement.

Both X11 / A2 appear to be the same board but with processor variants and some extra features in the X11. 

Unless anybody can spot something else, the 'customization' seems to be the switch of processor on the a2 board and removal of the vga port.

If Supermicro were THAT good in general, maybe we could learn something from that €20,000 SGM Extreme Server and try this with ECC RAM?

 

https://www.supermicro.com/products/motherboard/X11/X11SCL-IF.cfm

 

Granted an i3-8300T might be somewhat difficult to get when compared to more common ones, though its 35W TDP should be good for a fanless setup

https://www.servethehome.com/intel-core-i3-8300-benchmarks-and-review-the-dark-horse-low-cost-server-processor/

Quote

Unlike most of the Core i5 and Core i7 models, one can get unbuffered ECC DIMM support in the Core i3 series.

 

Other than that, they also have something else with 16 cores / 32W TDP but we're talking about a motherboard for $779

BTW, I wonder if they're actually paying Supermicro to tweak the BIOS or not?

They have removed a bunch of componentes too - the DP to VGA convertor chip, the actual VGA chip, COM port, etc. It makes sense. Those VGA chips are probably generating a lot of EMI.
