It's not great, stamped metal; the bar you can see at the rear is a flat piece with a slot cut out, this is where the signal (+) goes.

Construction like that makes me laugh when people get all anal about 75ohm RCA plugs that cost a fortune...
That's certainly not the best, but quite a bit better than the HD621.

It's ok to be stamped metal (not great but ok), but how it's constructed/mounted is important.

It appears that gold shell is one piece and directly soldered to the PCB board.

The HD621 that pulled out doesn't look that way. Just pressed into plastic. with no flange.

I think you'd have one hell of time pulling the shell out of that 518 socket.
But still considered a "cheap" socket, just better designed.

Not sure how the older stacked ones were built.

Even on an old 561 the RCA's varied. The Digital Outputs look much better than say the Video RGB ones.

Same goes for G61. The Analog/Digital Outs look solid (not stamped) but all the I/O is stamped. Hard to know if it's HD621 grade or 518 grade. But there is a small flange on them (on the outside, which would help against wiggle but not sure how much resistance there is to pulling the shell out)

I agree about the comments on cables. Sometimes you are better off with a "cheap" cable on a cheap connector, so as not to stress it.

If you think listening to music is fun, try learning an instrument.
