No, but that might be confusion caused by myself in earlier posts. The very first dashboard / FFT is via USB, then there are S/N ratio measurements via analogue.
I picked up earlier that the per Paul Miller's measurements via S/PDIF indicated much lower noise in comparison the analogue input, but missed the point that Amir's very first test was via USB.
Interestingly, Paul Miller's measurements also show lower noise via S/PDIF in comparison to USB, which perhaps lead to my own confusion.
With the input optical basically being S/PDIF from a protocol perspective, this could very well explain the higher noise floor.
