Hi @Marq,
Unfortunately the NAP300/500 RCA to XLR leads are wired slightly differently and will not work.
A good dealer would be able to re-wire them if you’re so inclined.

Hi @Yorkshireman,
The new NAP250 does have Zobel networks (makes speaker impedances look more resistive and less inductive) and output resistors. This greatly increases stability with a wide variety of cables. We do many tests during dev. FYI there’s also other compensation networks within the amp (1x lag compensation, 2x lead compensation)
This is the same as NAP250DR and the previous gen 250.
We do still find they sound better with a few meters of cable but no technical reason to not use short cables if it suits your setup.
Very early Naim could go unstable with some speaker leads e.g. Nait 1 didn’t have an output resistor.
Best
Steve

Appreciate that and thanks for your support on this thread.
No, not exactly a surprise, but a little nice to have it confirmed, I’m considering buying a 282 and a Hicap for myself. In what way did the sound characters differ?
Hi @Richard.Dane,
I had to consult Robin for this one 
XP5XS was used on ND5XS and provided all the power including USB charge currents.
XP5XS has the same PSU rails as XPS except in place of the DR regulator modules, chip regulators are used.
While not tested at Naim we do not see a problem to use an XP5XS on a NSC 222 via the legacy Burndy. I’m sure it will upgrade the SQ but by how much is yet to be listened too.

Thanks Steve - please also thank Robin for me.
Hmm, I am a bit rubbish at this stuff!
The 282 has a wider deeper sound stage, instuments are more separated, bass is tighter and more textured. Reverb trails are clearer.
The 222 is more of a homogenous whole with less defenition and depth. However the 222 to me sounds more fun and energetic.
I run a hugo tt2 and the Solstice with the 282, into SCM40A and it can be almost a little too clinical and revealing. I find the 222 more relaxing and forgiving. I suspect adding the PS to the 222 will bring more space and depth though and I would not be surprised if it then sounds better to me than the 282.
I also get the feeling that there is a bit more treble energy in the 222, but not in a bad way.
I hope that helps but do bear in mind that I have only had a few hours listening to the 222 and it is not fully run in.

You need to listen to system 1 for a couple of weeks, then system 2 for a couple of weeks, then system 1 for a couple of weeks, etc….
When you eventually loose the urge to swap system, that’s when you know which you prefer.

Obviously it’s the bigger 282 system that sounds much better
But is it much more enjoyable?
Not really… I do enjoy both immensely

I guess if you could run the Hugo Dac into the 222 then it will be good the compare the preamps
Now there’s different sources which is difficult to separate the effect of those from the preamps
I have compared the pre amps using my Solstice. My conclusion is the pre amp is definately the strong point.

Good comparison, using the same source
How good is the preamp of 222 compared to 282
I wouldn’t be surprised if it was equal or better

My desription of the 2 above was based mainly based on using the Solstice as I felt it a bit unfair to compare the streaming section vs a 4k DAC and 1.2k streamer.
In summary the 282 had more air and definition/detail. 222 was a bit more “fun”

So not a massive difference, then ?
No, not massive (to me). In a number of ways I prefer the 222. My room is well treated but don’t know if that helps the comparison to be honest.
I think it comes down to what style you like and whether you can be bothered with the whole tweaking to get good sound as you move up the scale.

I’d be surprised if a 222 bettered a 282 if these can be compared - they most likely can’t with same power supply ?

I’ve got similar results by comparing say a Supernait with Superuniti.
I believe its a matter of transparency which is higher on the analog preamps.

I don’t think when at that kind of level differences are ‘massive’ in any situation?
Surely it about personal preference of presentation; and whether one can live with very small differences longer term.

The volume control of the 222 is better than that used on a 282
