The point has been well made that as far as speakers are concerned there is (and historically has been) quite a bit of crossover between pro and domestic.
What about sources, amps and so on? There’s a small (historical) crossover of reel-to-reel and some turntables (thinking mainly of DJ and broadcasting TTs such as the good Japanese direct drives and e.g. EMT). And I guess there’s also some crossover with the odd DAC (Benchmark, RME and a couple of others). But beyond that?
Naim started off selling their amps into professional environments, including Capital Radio. I'm not sure how much their products ever got into recording studios, or how long before it morphed into basically a domestic hi-fi company, as we know it today.
