202 200 is a hell of a way to start a hi-fi journey (and can confortably be an endgame for a great number of music lovers). The Neat and PMC suggestions are great (PMC db1i is the same model as db1 Gold, they changed the naming at some point. Another great speaker to look into for a room that size is (again, on the SH market) B&W PM1 (but they must have their own stands, I tried them on third party ones and they didn't work that well). If small standmounts with surprisingly big sound are your thing, the PMC db1i and B&W PM1 would by my go-to.
Speaker cable is also important with Naim amps, so if they come with Naca5 you're set. If they don't, look into purchasing a pair of 3.5m lengths of Witchhat N2 (witchhat is a small company made of ex-naim employees who make Naim related upgrades - the N2 cable is very close to Naim's own Naca5, but you can actually bend it).
Another speaker to look into at your budget is Quad S2 which sounds absolutely great, but you have to give it some space from the back wall. If you can give them even more space and can accomodate their size, Wharfedale Linton are also well worth checking out.
Getting your source sorted is also the thing to do. For the money, you can't go wrong with a Bluesound Node 2 - it's got a decent sound and a great app. Cambridge Audio CXN v2 sounds better, imo, but the app is worse (although it's Roon ready or compatible). For a more appropriate source, maybe you can find a Leema Elements streamer on the sh market - it sounds very, very good and matches great with Naim.
