Hate to break it to you but Denon, Yamaha, Luxman and a few others all do their own caps. It seems pretty common with Japanese makers. If the maker has the economies of scale and is horizontally integrated enough they can and do. A few are even in a position to make their own screens on their streamers. They all make their own transformers too.
Naim is still small and niche enough whereby that simply isn’t possible on several levels.
One does wonder about the point of a screen, other than to make it look flash. The ND5XS2 manages perfectly well without one and in six years with a Naim streamer I’ve only used the screen for setup that cannot be done through the app. Just think of the money and hassle that could be saved.
Do they really make the capacitors themselves or are they buying so many that they may specify that their’s are branded with their own name by the actual specialist manufacturer?

Impossible to say. Japanese companies are highly diversified with multiple wholly owned subsidiaries. I know Toyota own the company that makes their screws (for example).
Yamaha and Denon are certainly large enough to produce their own caps.
I bet Yamaha, the HiFi company, as we know it, does not make capacitors in house. They are part of a huge conglomerate that separately manufactures motorbikes, pianos, boats, and god knows what else. Perhaps they even own a huge capacitor factory that makes 50% of all capacitors made globally - such is the way of the world these days.
I suppose you are going to counter that they actually make a handful of boutique capacitors in house, but you get my drift.
Presumably a lot of the features are available on the ND5XS2 which hasn’t got a screen, so they must be implemented in the code, so would it be that hard to have them also available via the app for the NDX2 and ND555?
If anything, the new streamers are the opposite. Some of the menu is only accessible on the app. I also find it bizarre that the fancy new Zigbee remote and colour screen cannot be used to play music from your NAS or Tidal.
