When Naim changed over to BNC's in the late eighties we used to call the Bloody Nasty Connectors. Nothing against BNC per se, but putting them on the phono section of Naim's preamps at the time when most Naim customers had Linn Sondeks with RCA tonearm cables was just sheer perversity!
Why so few devices with BNC's??
It's an ongoing amazement to me how many manufacturers use RCA's for 75 ohm digital connections. Is this really to just save a couple bucks? Lower end McIntosh stuff has RCA's as does most Japanese gear regardless of price. It's not like BNC's are really so exotic, and 75 ohm cables are readily available. In fact, the general lack of inputs is an annoyance. Not everybody wants to use USB or Toslink. Rant over. 😠 Thanks for reading.
