They probably believe in better switches and Ethernet cables. But for commercial purposes they prefer saying that their streamers don’t need additional costs to work optimally.
It’s the same for all brands.

Apart from anything else, it would be a significant time-consuming task for Naim to evaluate all, or even just a sprinkling, of the swirches and cables on the market, and in the different permutations of connection people have described just in the 3 month life of this thread, and with each of their streaming products. And that would only relate to the electrical environment and possibly wider network connections of their listening room.
Add to that new audiophile Ethernet cables and switches being marketed seemingly frequently now the specialist supply manufacturers have cottoned on to this new market, and the potential problems that could arise for Naim if they openly favoured.or disfavoured the products of other manufacturers, or omitted to test others, and I can fully understand them not getting involved. Given this, it seems to me that the best one might reasonably expect to get out of them is information as to what network srtup and components they actually use when testing their own products that use Ethernet.
Why not summarise this thread and sell it to Naim …
No, that’s not really the point. I absolutely wouldn’t expect them to be testing everything and/or recommend anything specific but simply acknowledge that differences exist.

Well I kind of disagree … naim have gone to the effort to make the Statement Amp/Pre Amp at huge expense … this by its very nature is pushing the envelope…to demo this when it is clearly being significantly restrained … seems nonsensical. It was clear to me - that the view was bits are bits… it categorically is not. However, I see your view - that maybe could hold true for Atom/Unity but not the classic upwards.

The new room does (maybe) have a ha’p’orth of tar missing. I suspect the room is connected to the whole building LAN & as such a lot of client attached & open outlets. Whatever it does appear to have missed some ‘audiophile inspirational’ stuff in the ethernet department if nothing else to have a typical demo home installation.

There is a sensible limit - to be taken no doubt …they were using powerlines and SL throughout which is great…I think someone needs to go in there and do a demo using good switch and ethernet cables…say with a Cisco or Aqvox switch and maybe AQ cables… I think they would be very surprised.

Sounds like a job for Peder to take on because he is adamant that everyone will hear the differences when done his way, even in lowly systems, though whether he can persuade Naim that Tune-Dem is the be-all and end-all of assessment might be another matter…

I am sure Peder would do an epic job. 
I have a vision of a viking long boat off the south coast armed to their teeth with cables and switches…would be interesting.

Maybe better if Naim just try it themselves, it’ll save a lot of forum space.

Innocent_Bystander,…And I Build That Position On…
Almost 26-year of professional music-system installation-work,from 1994 to today (see also my profile).
With a method,.Tune-Dem,which Linn invented. And as both Linn and Naim used at that time,.what Naim does today,I don’t know.
But Tune-Dem is still the method,.as Linn uses in all his evaluation of their products,music-systems and set-ups.
I have also from 1983 until today,.been involved in,and evaluated music-systems together with,.among others…
Ivor and Linn and Naim’s previous distributor in Sweden,.to various Swedish top-designers in hifi.
These,.who have their products on the world-market,down to ordinary evaluation-meetings with us consumers.
On many (most) of these occasions,.I have also had the responsibility,to made the changes in the music-systems in these evaluations.
And on none of these occasions,.someone has had a dissenting opinion on what has been…
• Better - Worse or just Different.
Innocent_Bystander,…I notice your slightly mocking tone between the lines,.but to be honest…I Don’t Care.!!
I think so too,.I definitely don’t feel insecure taking on that task 
.

Not mocking ( I never mock anyone other than jest) but unconvinced that everyone will hear, and unconvinvced that Tune-Dem is tge way to decide which is better- it may help tell a difference, but as I have offered several times before, following the tune, even of of every instrument, is not of itself a certainty that the spund will be better and more engaging to any particular individual. For that other aspects and/or much greater listening time may be needed.
However, if anyone is to convince Naim’s sound quality setters that cables and switches make a significant difference, I truly believe you would be well placed.

Peder…It would be brilliant if Naim would let you show them. That statement setup is capable of so much more…
Quite agree. Maybe if lots of us backed it and there were a number of setups to be available for comparison that people here agreed upon. Would be nice have factory visits to hear the results.

They already know this,.but it is as @frenchrooster says…
If they didn’t know,.or have noted this,so I would be very surprised.
Innocent_Bystander,…There is no idea to discuss this with you,.this because you can not perform the method.
I’ve seen you make negative statements in the past about the method,.it seems very strange because you can’t use the method.
And when you do it,.well then you question the basis of,among other things,.Linn’s development-work for decades.
You really need to have…“a lot on your feet” as we say in Sweden,to do this.
And we know you don’t have that,.because you can’t use the method.
It’s only a month since you wrote in a thread,.that when you got the time,you’d read more about the method.
I have also told you that this you must learn by practically practicing on,.together with someone who is already knowledgeable on the method.
That’s why I say,.“There is no idea to discuss this with you.”
/Peder🙂
Quite frankly, I very much doubt Naim need showing anything. I’m sure they do their own experiments.

For ethernet cables b/w switches and streamers/NAS is there a length that is too short? I’m using 5 feet currently but 3 feet would work for the NAS and eliminate some excess cable.
I prefer 1m fas a minimum, mainly for easy of connection and lack of stress on the cable. Otherwise, I believe the shorter the better, but I’ve never done any comparisons.

I’ve been continuing my experiments with the the EtherRegens.
The Ciscos sounded better away from the Naim racks, but the EtherRegen seems to be less fussy about being on them. It definitely works better as close as possible to the Naim 555 as Uptone recommend (1m Ethernet cable), which is what I am experimenting with now.
I have one near the Router and Roon Nucleus and the other on the stack at the end of a 5m Ethernet cable (the DesignaCable Belden CatSnake Cat6a).
It makes quite a difference like this. I had a little wow moment the first time I connected up the second ER on the Naim racks.
Get the EtherRegen on the quiet stack, though - and of course away from the 552.
And don’t be hasty about making judgments when auditioning it after a power down to move, though. Even if still warm it takes a while to get completely back on song. Immediately afterwards it is more layered and detailed, but also coarser and more in your face, with textures suffering. This then gradually calms down, fleshes out and matures.
