Hallo, ROlin - thank you very much for your fast mail and explanation. Though the concpet looks very intersting for me, I fear the 960 kHz are two small for my monitoring purposes. Very sorry to say so ...

Hello, Nils.

No, it is impossible.
This device is used 100Mb core LAN9115 and USB3 to LAN converter in the same modification.
So maximum speed connection can not be excess of 100Mb

Table of required connections speed for one receiver.
48k - 4.5 Mb
192k - 11.3 Mb
240k - 13.6 Mb
480k - 24.9 Mb
960k - 47.5 Mb
As you can see, 2x960k nearest to theoretical limit of speed. This will work with LAN or USB connection if you will have  enough powerful computer.
But for WiFi connection with LAN/WiFi version, maximum speed will be only 70 Mb. It can possible to use only 1x640k or 2 x 384k sample-rate maximum.

Why are there USB or WiFi/Lan versions of this device ?
1 - it is convenient
2 - it is increase the interferences from LAN connection. If you have planned to use simple antennas like Long Wire - you need to think about that. See included pic. Was used PA0RDT Mini Whip antenna near to tranceiver.
