i had the opportunity to demo a 300npx with my 222-250.
what a mess the burndies, a pain to insert and lock them and even greater pain to take them out.
i am going to return the 300npx … with the burndies inserted as i could only take them out on the 222.
is naim properly testing the equipment?
they think it is normal to have these stupid burndies? i am “really” impressed.
what a disappointment.
More to the point, did the NPX300 improve the sound?
The npx300 is barely used.
Initially, no, maybe because i hadn’t locked the burndies.
Then i tried again and it seemed to improve but i was not convinced, i took it out and the sound without seemed more fun, agile, engaging … until it started to sound more thin with less information.
I am trying again and the answer seems to be yes.
It’s similar to going from (2)82 to (2)52 or cdx(2) to cds2(3).
Initially the fun factor seems less, but when you go back, that’s when reality kicks in.
I was expecting more but have to wait some more days, the npx300 is almost new.
PS - I play tennis several days a week and almost damaged my right hand fingers …can’t do that i need to hold the racquet properly. I was/am pissed with these burndies.
Burndies have always been tricky, especially for those with arthritic hands.
Posted about these pliers - note the version with the plastic grips - in a different thread.
First spotted them in a Naim dealer, so burndies are not an easy fit, but benefit from a tight connection by design. Two colours silver and black, pic from the big river.
NSC222 + NC250 here in a second system. Adding NPX300 in one room with good acoustics was a worthwhile addition. When tried in the systems usual location, a poor room acoustically with speakers in the corners of a shallow alcove, the difference was not enough for it to remain; ymmv.
the sound is more mature, presents (more) information in a “relaxed” (less in your face) way, with great agility and prat.
there is more the feeling of sounds emerging from nowhere, more space between instruments, easier to follow each instruments.
treble a bit smoother.
bass a bit more muscular (fuller and deeper) but tighter.
easier to listen at lower volumes (the sound is already full) … and higher (it can go louder without one noticing how loud it is).
more dynamic, this to me translates to more real and convincing
more delicacy when necessary
in spite of all this, i was expecting a bigger npx300 improvement, i guess the 222 is stretched to the limit, it can’t do more.
it does remind me of my previous cds/555psnonDr-252nonDR-300nonDR, but being cleaner/faster.
is it better? i am not sure.
NC seems to have less weight and rawness to the sound, which sometimes (to me) can sometimes sound less organic and more “artificial”; but it can also sound faster, cleaner with better prat → more engaging
anyway, going back to OC is not an option. 3 fraims less, 1 powerline less, 1 hi-line less, only 3 boxes easier to put in my small room (just one stack of fraims), and i like the sound.
my brain will adjust in a few days as it would (also) do with OC
had i not listened to the 300npx, it would also adjust to the 222-250
When I first received my NPX300, the Burndies were so tight they would not fully lock on either the 222 or 300,
They were both promptly replaced by Naim and have fitted flawlessly ever since. This was apparently an issue with a number of 300’s/Burndies.
And the NPX300 does make a significant, immediately noticeable improvement to the NSC222.

Crikey I was looking at getting a pair as I struggled with my cables, but they are £69 from Screwfix cheaper down the river.
With the part numbers a bit clearer from the Knipex site.
That’ll be because Screwfix pay their taxes.
Are you guys serious?
We shouldn’t need special tools to use burndies…
You shouldn’t/don’t need tools to fit Burndies!!! If they’re stiff/tight a wearing a rubber glove should give sufficient grip to lock then into place.
Given the restricted space at the rear of the 222, if a tool, eg Cannon Grips, were to slip, you’re quite likely to damage adjacent connectors. Alternatively, if there is a real fault with either the Burndy plug or socket, excessive force will damage one, other or both.
Don’t say you haven’t been warned.
The OP should insist Naim replace the Burndies supplied with his NPX300, whether it’s new or s/h, as they did for a number of other customers.

Perhaps try reading the first sentence of my post # 4 above, before passing judgement.
..ditto..
The judicious use of tools in such a case is not about using excessive force (although these wrenches do make that easier). It’s about applying the required amount of force on exactly the right direction, which isn’t always easy when setting up a rack of equipment with limited space.
There does, however, seem to have been a spate of problems with New Classic Burndies. So yes, if they need more torque that you could apply by hand I would be asking Naim for a solution.
Agreed, like I said, I only had to ask for a new pair of Burndies and Naim provided them in a couple of days…. .
ATB, J
NOT judging, so enough of the passive aggressive responses.
And surely those with restricted hand/wrist mobility are even more likely to damage their expensive Naim kit trying to force fit Burndies with a pair of Cannon grips.
If the supplied Burndies are too tight to lock properly, get Naim to fix it. This issue hasn’t been mentioned for ages, so obviously Naim rectified it and will no doubt happily replace those remaining Burndies which appear over time.
ATB, J
I can echo the same experience with them, and I asked my dealer to get me a new pair which was much easier to install. Seems like there’s an early batch that is really hard to fully lock.
The npx300 i have at home is a demo one
Buying a new one, hopefully will come with better burndies
I will have to bring my SL2s a bit more foward, away from the back wall, because the sound now is way fuller and can sound too much for the room.
Maybe so, but last time I had to remove the one on my 552 PS I had to use a pipe wrench, and I don’t have a limp wrist. Better than cutting the cable.
