My new interface module for wired Ethernet, "Interchange" is finally working. It gives me Ethernet input and S/PDIF, AES, and I2S output. I will be comparing it to my partially working XMOS Off-Ramp 6 interface today. Right off the bat, it seems to sound very good and works at all sample rates. I am using Jriver so far.
It draws a lot more power than the USB modules did, so I will need to change the Dynamo from 12VDC to 9VDC in order to reduce power dissipation. It think it may be okay inside the ODSX however.
