A lot of this may still be helpful to some:
Hi Daren,
Sorry, that was me. I gave two sets of information to Marketing. (I’m Steve Sells, Technical Director of Electronics at Naim…or 110dB on this forum).
One set of information is for the manual and website, the other is for technical press.
We normally quote 8ohm power and always at 0.1% and will continue to do so.
The 4ohm, 2ohm, 1ohm and burst specs have been written for technical press in mind. Marketing liked my technical press spec and have included some of it in the release info and website. I do not have a problem with this.
I’m pretty strict to stick to IHF-A-202-1978 guidelines for specifications. i.e. in this case:
Use 230VAC, increase 1kHz signal until the amplifier is just clipping producing a distortion of 0.1%. Then add some margin.
(Some valve manufacturers would quote 1% THD because they could make 0.1%.
Remember the ‘Leak point-one’ amplifier because it could do less than 0.1% THD)
Best
Steve
PS I apologise it looks like some of the fonts and numbers in the spec have not copy and pasted too well from the master doc. Marketing are quiet busy this week, we’ll give them time to tidy. e.g. ‘Burst power 2’ is meant to be ‘burst power 2Ω’. Not all font packs have the ‘Ω’ (Ohm) symbol.

If that’s the case Alley Cat I’d just keep them

That depends. Again appears to be references to Derek and Clive here

NSC 222 to “Active” ATC SCM 40, sounds like it should be a big winner!

From our listening tests it’s above XPS DR…Some dealers will be opening theirs today and will report back too

I dabbled with the idea of adding one, borrowed a demo one for a bit, never ended up a permanent fixture. I’ve been more than satisfied with the current 2 box setup for a while.
The new PSU seems a more cohesive “enabler” and lays a path longer term for a next gen NAC/NAP setup, keeping the NDX2 in the mix.
Oh my word!
There I went and quoted you earlier today and did not know you were answering my questions about it!!

Thanks, Steve…
Its good that you have ‘outed’ yourself…! I was wondering who @110dB from Naim Staff was…
So, the traditional, or old style Naim 4ohm output of the New Classic 250 is…??
(where the ‘original’ 250, like mine for 1985, was 125W - times 2 is 250W)

Nothing better than a CB250

Yes, there is… A CB 250 which is in Olive clothing…

I must have missed that. This is a long thread to read lol
Sure to be a winner, that was always the doubt with the Atom HE as a preamp in to active speakers, I explored that as an option last year and the overall conclusion was along the lines of “works but not ideal”
Hi all, does the NCS 222 have the AV bypass function like my Supernait 2.
Hi Steve
How much of a difference in SQ is there between a 250DR (with a SL interconnect) and a new Classic 250 with the supplied lead
Also is the eddy current part that is new on the new classic 250, something that can be retrofitted to an older 250DR during servicing?
how does the new classic 250 compare to a 300DR? From what I know about Naim, the 300DR will still sound better ?
The “problem” is that speaker design over the past decades has moved further and further to requiring more and more current – even “small” speakers.
It’s not about how loud we want or need our music. It’s about the “efficiency” of the speakers. And it’s about whether one choses to provide enough current to let the speakers work as intended, even at quite moderate listening levels.

Or a pair of CB135s in olive livery (mine are serial numbers from 1984 and were put in olive sleeves at the factory before I bought them in 1989 or ‘90).

No, it’s not a strategy mess, it is a move towards the statement XLR connectors, which is the way forward. It is good Naim is now using the connectors that for example, Linn and Chord electronics are using themselves to ensure more compatibility.

Yes, I can see where the 300 series is the full-separates series. Naim are a performance company, so I can only expect that, if any rumors of 282/252 demise are true, that any replacement into a single NAC in the series would have to perform at at least a current 252 level? Or, are there multiple NACs? 
I’m leaning toward a single NAC in 300-series to keep things simple: 200 series with combo capabilities e.g. NSC-222, step up to full separates with 300-series, and can use NPX-300 as stepping stone, and then 500-series for ultimate in [new|legacy] Classic range. A revision of the 500-series would also be interesting e.g. using similar approach to single PS (NPR-500?!) and using that as stepping stone to get to new 500-series components.
In addition to any “new” NAP-300, I’m wondering then about the performance of the current NPX-300: if we assume, again, that Naim’s performance priority is to not take a retrograde step and that this new PS will be “the one PS to rule them all”, then is the performance level of the NPX-300 at least comparable (or exceeds) current SuperCap? I would imagine it would have to be so, if this range is to replace the current 252/SuperCap ultimately.
But, I expect application of NPX-300 will be limited to new NACs/Streamers/NVS only and not applied to older Classic range? TBD.
