stavrose, thank you for your question.
It took a few years, but I sorted out my Naim boxes first.
Source: NDX 2/XPS DR
Preamplifier: NAC252/SuperCap DR
Power Amplifier: NAP250 DR
Power Conditioner: Audioquest Niagara 5000/Audioquest Tornado High Current power cable
Power-Line full loom
SuperLumina full loom
The NAC252 and the NDX2 are on a Naim Fraim.
The XPS DR, the SuperCap DR and the NAP250 DR are on an Isoblue Hifi rack.
My “old” digital front end (modem, Cisco 2960 switch, Roon Nucleus/Ferrum Hypsos power supply, Chord Epic streaming cables) was fine until I upgraded to SuperLumina.
Thanks to excellent support from my dealer, I was able to sort out my “new” digital front end.
Modem > Network Acoustics eno2 streaming cable (1.5m) > Network Acoustics eno2 filter > Network Acoustics eno2 streaming cable (0.75m) > Antipodes K40 music server > Network Acoustics eno2 streaming cable (1.5m) > Naim NDX 2 music player
My Antipodes K40 music server is plugged into a Yeti Acoustics 1000W Standard power conditioner/Yeti Standard Plus power cable.
My modem is plugged directly into a wall socket.
I live in a small space, so I do not have any long runs of cable.
Also, my network is very simple: a laptop, a tablet, a music server.
While the Roon Nucleus/Ferrum Hypsos benefited from the addition of the Cisco switch, the Antipodes K40 did not.
I auditioned a second Network Acoustics eno2 filter (placed between my Antipodes K40 music server and my NDX 2 music player), but it compromised my system’s pace, rhythm and timing.
I tried using one Network Acoustics eno2 filter placed between my Antipodes K40 music server and my NDX 2 music player, but it upset the tonal balance of my system.
What works best for me in my set-up is one Network Acoustics eno2 filter between my modem and my Antipodes K40 music server. I am guessing the eno2 filter is removing the network noise generated by my modem.
The amount of cleaning/filtering your set-up will need will depend upon your network and your set-up. In my opinion, there is no “best practice” solution. What works best for one set-up may not work best for another set-up.
Adding one Network Acoustics eno2 filter after my modem reduces network noise without compromising the music.
At some point in time, I will demo a Network Acoustics tempus switch. To be honest, I have no idea if it will make my set-up better, worse or if there will be no change.
