Ethernet connection problems
Beantwortet
Have a Node 2i. When installed some months ago the ethernet connection sounded slightly better than the wireless connection. A couple of weeks ago I noticed a sudden marked decline in audio quality: no dynamics, fuzzy bass etc. After extensive fault finding I found that the ethernet connection is the problem. Wireless works perfectly but ethernet is severely distorted. I have rebooted wireless router, factory reset the Node 2i, changed LAN cables etc etc. I am quite happy to leave it wireless but can anyone suggest what might be going on? Modem is TPLink VR2800. Sources are primarily Tidal Masters, but also Radio Paradise and Roon local library all show same problem, regardless whether using BluOS app or ROON. I am suspecting an earthing or noise problem on the ethernet connection or a hardware failure of the ethernet interface.

On further investigation I note that all my audio equipment and video equipment are either smps or double insulated and that none of the four video components, four audio components and three routing/computer devices has a connected electrical earth. The video and audio components are electrically connected only via the shielding on the antenna leads to the FM Tuner and TV which connect via a diplexer to the antenna system. I am wondering if I should connect a separate electrical ground wire to the amplifier chassis (via turntable earth point) to provide an effective star ground to the whole system and hopefully thereby reduce SMPS noise which is probably being transmitted over the LAN cables from router to Node 2i and thereby causing the problem described above?

Problem solved. Came across some excellent technical papers from Auralic on the subject. The fix was to implement QoS rules on the VR2800 modem/router. As a result wireless is now working to an extremely high standard. The Bluesound Node 2i must be configured with a High QoS rule by itself at a 60% priority level. QoS is turned off by default on the VR2800 and must be turned on. My best guess is that implementing QoS is reducing jitter to the Node 2i.
Regardless of the reason, TIDAL MQA Masters is now sounding better than a local 192/24 KHz FLAC file of same track on a USB stick. I also find the BluOS app still sounds better than ROON, esp on MQA.
