Naim Audio system owners - What speakers are you using with Naim?

My main system is full Naim 500 series with passive Naim NBLs, I used to have a 282/250 on them before that with either a Hicap or Supercap powering the pre. Before the NBLs the 250 was running into Thiel CS1.6s. When I bought the Thiels the dealer demoed them with Accuphase and they really couldn't produce any excitement from the likes of Tool and even with Scriabin there was a haze around the piano. I nearly didn't try them at home but I'd run out of all other options locally so gave them a go. With a 282/250 up them they took on a somewhat livelier character and earned their place. As my source was upgraded it started feeding a bit more low bass into the system which was exciting a room mode, not helped by the ports on the Thiels, the NBLs were taken in part ex by my local Naim dealer and I didn't think they'd work in my 4m X 3.8m room but we found a spot where they work a treat, I doubt I'd get many full range speakers to work in that space. I still have the Thiels and 282/Hi/250 in a second home and there I have 6m X 7m for them to breathe in but bass is there a bit light. When I set that second system up my wife said she'd missed that sound and there is something about the thiels, though the NBLs have them on rock. I'd love to try some 3.7s with the 500 series in that room against the NBLs and might get the chance when I retire next year, if I can find a pair.

Naim never ceased trading so “going under” doesn’t quite ring true but it was rather disappointing to see them merged as a junior partner with Focal. It was done in order to fund development of their streamers. Focal then being sold to venture capitalists was also rather worrying but that was a few years ago now and they’re still thriving. 
They could have suffered a similar fate to Thiel, that was a sad end.
