Changing ethernet cables or otherwise optimizing the ethernet does not make a difference with the N30SA here (in contrast to my old Aurender S10). The isolation of the N30SA LAN port apparently works very well.
The N30SA wants the best power cord you can get, wants to stand as vibration free as possible. It talks to my DAC over the SPDIF protocol via an 110Ohm XLR cable, aka AES/EBU. I found this sounded better than SPDIF over RCA. I use an in-akustik air-silver cable.
I put the N30SA onto IsoAcoustic Orea feet. It hates vibrations.
The N30SA is a beautiful naturally sounding device. I mainly play local files but even streaming sounds good. I have not heard any better music reproduction outside of ultra high end analog.
