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.

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

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.

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.

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.
