I would guess at some form of technology tie-up with a much larger business, with products being labelled as ‘developed by Naim’ (as in quality terms they punch well above their weight and physical scale). This would play to Naim’s development and music-quality strengths, with things like app software being developed by a.n.other.
But the 11pm time suggests to me something much more benign.
I would be surprised if it’s a new Salisbury product… as production has been hit with Covid 19 and I suspect it would not have been possible to do the intensive build runs required for most new products with all the required social distancing safety requirements…
