Improving streaming input

As a result of a series of trial and error tests here are my suggestions for improving the quality of input to the streamer:
1. replace the stock cable beween router and wall jack with a fully shielded quality cable.
2. add an LPS to the router replacing the noisy wallwart
3. Use a high quality, short Ethernet cable between router and house loop. (e.g. Meicord)
4. Add an Ethernet Isolator/filter just before the streamer (e.g. EMO EN70–HD)
5. Use a short, high quality Ethernet cable between Isolator/filter and streamer (e.g. Meicord)

In my experience there is no need to reclock the signal before the streamer. Conversely anything that helps prevent noise from travelling along the Ethernet connection helps (e.g. ferrites). 

Enjoy the music

Here we go again: the bits are bits crowd has woken up again: No, there are no lost bits in ethernet transmission and all‘s well in the digital domain BUT:

Along and WITHIN the digital channels on ethernet, the cable and boxes collect ground level and EMI/RFI level noise. While that has no effect on the digital end it messes up digital to analogue conversion and puts additional strain on the server‘s and DAC‘s CPU, which is very well audible if you care to listen rather than argue from first principles. In other words: you have a problem in the analogue domain, and no, the noise rejection of these devices is not good enough to entirely defease it.
