I can see text (quoted below) and can read the jitter measurements which do indeed appear to be 8x lower with ethernet, but I have to confess that I can't see where it is that the measurements or graph show the 200Hz component or see how significant it is- however Linn seem to think it is because the DSi is streamer/dac/amp and still think its insignificant.
"..... indeed there is an additional jitter component at 200Hz during Ethernet playback. This is caused by processor loading of the power supplyduring Ethernet playback there is processor activity at regular 5ms intervals. The Majik DS-I is an integrated product that inevitably does not have such good power-supply isolation between different parts of the circuit as we have in the Linn DS source-only products. There is a small element of the 200Hz getting to the DAC's power supply, and this is apparent on the measured graph. It is worth noting that this disturbance is not audio-correlated, so is unlikely to have an audible impact."
