Just found a Naim White Paper that @110dB has written, on Balanced Connections.
It’s on TomTom’s site, so I will not link it here… 
I could not find it among the White Papers listed on the Naim audio site…?
Maybe @110dB or @Richard.Dane can provide a legit link…?
I’ve sent Naim a request.
Oooh, nice, been wondering about when that would turn up. Thank you for the heads up
What would you recommend as a first step. Upgrade to the 222 or NC250 with a 272/XPS (or 555)/250 system?
My XPS DR has no buzzing or humming issues.
Great @Stephen_Tate ! It means that you don’t have any DC offset in your mains or that your XPS is within perfect tolerance. For toroidal transformers, sometimes it’s like rolling the dice… but if your network is clean then it’s even better!
Have you tried removing and then replacing your farad super three PS since you got your new system to see whether the difference is greater than it was when you first installed it?
Nope, have not. I sold the Ifi so would only have the original going back to. They offer free try before you buy so no risk trying at home if interested 
Not mine either..
I rather think it’s time to replace my 272, Slamdam. At least in the long run.
I got the sense you wanted to keep the 272 for a while and update things around it 
If everything is on the table I would also replace the 272. I couldn’t wait for 222 so went another route. Many ways getting happy with naim
@110dB just out of curiosity, why does the NC250 have a factory reset button?
Hi @nicnaim,
NAP 250 has an ARM microcontroller that runs background tasks such as the inter-product communications. The rear control PCB is common to other products.
A reset button can be a good idea with any product that has software.
The reset button is also the LED brightness button (dual function).
Pressing the button manually cycles through the 3 brightness levels. This is used when not connected to another product such as NSC 222. When connected (via optical coms) the two units a synchronised i.e. the NSC 222 app controls the 250
Hoping the 222/300 I have on order, arrives at my dealer’s today, which was the predicted delivery date sent by Naim to my dealer when I ordered it on the 5th Jan. My fingers and other digits are crossed. Also, have my upgraded LP12 ready, so it could be a weekend of many changes to my system.
5 weeks in with my 222/250/300 and I have encountered or should I say my wife has encountered a serious problem since having this new kit 
It sounds so good I am listening to music instead of checking off the to do list she provides me 
Have you noticed much change in the sonic signature as it’s settled in? If yes, can you characterize the change?
Yes, there are many ways. This is at my dealer right now, the market for old Classic products has started to move in Sweden..
No regrets going 552/500 here. Just sold my 300DR and I’m sure the guy will love it You should evaluate upgrading in classic range too these days when prices on new is extremely high. You can reach a 500 amp for about the same money as the new 250. Something to evaluate. 500 is sick! 
Not really, when I first set it up it sounded a little bright / less warm than 272/250/555, however, I then put the radio on for 24/7 for 5/6 days before going back to it. Since then I had one moment where an album sounded awful (complex arrangement) so I stopped listening and put the radio on again for a few hours.
Now to my ears it sounds like a ‘Naim’, differences for me is the increase level of detail even at low volumes (for example I currently have it on 18 listening to a Wilco album and all of the subtle elements are present) and the ability to drive at low volumes also (my fave Miles Davis album Jack Johnson I would normally crank up the volume to get ‘the feeling’ but now no requirement to).
I can’t really demo here, unfortunately and I have a few questions since I’m in the process of moving on from nac82/250dr. My questions are 1. Does the new gear have the drive of the old? Reason for asking is my recent experience with Goldnote P1000/PA1175 which has a wider and deeper soundstage and more detail but not the same drive. It’s got drive and momentum forward but is smoother so to speak. Does this difference resemble the differences between Naim of yesteryear and the new gear do you think? Or does the new Naim manage to combine the rawer drive and momentum of the old with smooth and detailed and deep and wide soundstage?
