I have not seen a locking RCA. Could you enlighten me?
The reason I like the way XLR's lock in place, is primarily when I am swapping out one piece of gear or cables from my pre-amp. I have to push my pre to the back of it's shelf, disconnect IC's, reconnect IC's, and then pull the pre-amp back to the front of it's shelf. As carful as I am, there is always the risk of an RCA slipping out(It's happened to me before). Not so with the XLR's. I'm sure that many members can relate to this issue. Again, I am NOT referring to any sonic differences between the two. That's a whole other can of worms.
