I did all my tests without any DSP (neither in Roon, nor in Devialet), so as not to influence the result.
However, what intrigues me is that there is a difference, although it is the same system, both protocols are bit-perfect, both use the same input to Devialet (Ethernet).
I understand the differences between USB and Ethernet inputs, but I don't realize where the differences in the same input (Ethernet) come from.
Moreover, the differences always appear, in multiple conditions (with switch, with router, with direct cable, etc.) and always in a similar way. The only thing that differs is the protocol used (Roon RAAT versus Devialet AIR), but both should be bit-perfect, so they should have had the same result when using the same input to the amplifier. And yet the result differs...
