For best quality streaming, yes to Qobuz, yes to wired Ethernet, but the network implementation is important. Cheap 4-way or 8-way network switches by D-Link etc. act as buffers to induced network noise. Change the included wallwart PSU to an IFi iPower unit If possible.Always place one of these directly by your rack and use a short very high quality Ethernet cable. Use it for audio only. To further improve the quality to surpass CD you must filter out the RFI in the Ethernet cable, otherwise this enters the streamer‘s circuits and upsets the timing of everything and will smear dynamics and detail/ambience in music. The Network Acoustics ENO filter is the business for doing this.
