Do you guys do a power weighlifting course before using these?
My dealer has set me up with an NPX 300 into my NSC 222, I want to evaluate the Power supply before buying-I just cannot get the burndy’s out of either piece of equipment-any suggestions?
Alternative interconnects maybe?
It may result in scrapping the PS idea as I don’t want to be running to the dealer whenever I want to move shelf or move house
The burndies for the new equipment is only for power, but split as I understand it in one for analog and the other for digital for the 222. The locking system used is something you have to get used to but not that difficult. I think there was another thread with a person with a similar p problemm, but you should be able to unlock and lock the locks on the plugs. I have not tried it on the new gear but on 252 supercap and 300. Especially my 300 was terrible almost impossible to get disconnect at the one end connected to the power amp.

Access to the Burndies is somewhat restricted, more so with the NSC 222. They fit easily enough, once correctly aligned, however, rotating the locking collars to the click-locked position can be very difficult.
Full disclosure - the first set of Burndies supplied with my NPX 300 were so tight they would not lock whatsoever and were replaced by Naim, the second set have worked fine ever since.
Naim suggested a variety of techniques to lock ‘stubborn’, ie tight, Burndies ranging from rubber gloves to jam pot lid openers (a rubber ring wrench). I would be EXTREMELY wary of the latter approach, especially rubber jawed aviation ( Cannon?) grips - the restricted access provides multiple opportunities for this not to end well - eg terminally damaging the Burndy plug/socket and/or adjacent connections on the NSC 222.
I found a small piece of rubber sheet, or a latex glove, offers sufficient purchase to lock the Burndies - if more force is required, demand a replacement set from Naim - they have been aware of this issue since the NSC 222 / NPX 300 were launched!
Good luck,

get yourself one of these, take off the yellow bit, the rubber part wrap around the Burndy collar and turn. makes life very easy, you’ll never be beaten by a Burndy again. I had to get this for my nap500, the heatsink is large at the back and makes it so I can get the leverage using my hand
Thanks
All my burndies are easy to remove - except 552 which is tight as h… Will order those at once 
they must vary then mate, my 552 is easy. 500 nightmare!haha
The 500 are totally fine - my 552 are so tight - the vary!
Bought it - what do you mean by „take of the yellow bit“
Yeh, 500 is a right mare due to the hear sink shape stopping your grip. One side is worse than the other. I just use a plumbers grip with the jaws wrapped in gaffer tape. It’s just that 1cm of movement that’s needed free them from the lock.
have done the same - with microfiber cloth underneath and very careful. But only for 552. 500 is nice and easy.
It’s only a few mm of movement and than it’s fine. But you can easily dismantle the Burndy plug by accident…
sort of an example of how to use it
its really to get the last click tight, and the opposite to undo it
Why doing this … does it have enough force with bare hands ?
Is it not working with the yellow housing attached?
yea its more than enough.
with the yellow bit attached I was concerned I might break something also the space is limited round the back of a 500
With 552 there might be more space as the plugs are at the side.
yea I think your right mate, doesn’t have the big heatsink. I was being cautious using any tools so took that bit off.
my 500 was impossible by hand alone, using one of these its nice and easy. because im holding the rubber bit I can control how much to turn etc
My experience of the burndies on 222 - 555 was much more difficult than previous kit. It does help to fully study how they work before getting to inventive with tools. Some gentle warmth could also help. I did eventually get them on by hand, but at one I really wondered what was going on!
I have a full arsenal of tools especially for the hifi Kit … laser distance measure t, mini spirit level, …
Mate I bet you do 
It’s all good fun with all the tools and bits n bobs
Thanks for the replies-I spoke to Naim about them this morning-no mention was made of a locking system???/ I’ve just been trying to pull them out.
With arthritic hands and active system, I can’t manage unaided. I use Knipex 81 11 SpeedGrip Water Pump Pliers, 250 mm Overall, Angled Tip, which one of the dealers I use suggested. A ratchet style arrangement means that just a gentle pressure can be applied; not cheap but work well imho.
