Because another part of the OP’s question was if it will have an effect on sound quality with the Nova and unfortunately the unequivocal answer is apparently not “no it will not, Naim’s taking care of it”
Lumin X1 is perhaps the only one to have a fiber Ethernet imput on the streamer. @Simon the great has said that it’s not impossible that Naim will integrate it in the future.
But as others have said, as for philosophy of advertising, Naim can’t write that their streamers are not optimally performing as such, that the customer has to invest in expensive switches and ethernet cables. Neither DCS.
I am reading other forums sometimes and very rarely find a DCS owner with a 4 dollars ethernet cable.
May I ask a clarifying question? Am I understanding correctly, that you are saying the last Meter of CAT6 cable which connects the Streamer to a Netgear GS305 switch (which in turn is plugged into a LAN wall outlet hard wired with industrial CAT5e to a patch panel, then another switch, then to the router) makes a difference? And that one should pay attention to it and not use just any CAT6 cable?
I don’t disagree necessarily with the philosophical questions, but I don’t think they are the point.
It seems that with a small investment, the very good Naim streamers could be much better. Naim sell more costly cables for the same reason. Would Naim not want their streamers to sound much better if it is so simple? I think they would. So why do they not?
Edit: I think nobody expects Naim to include room treatment, but we are talking about small change (if built into the system) that would give them a large advantage over competitors if the switch theories are true.
