As I take inventory of all my “stuff” . . . I find a SuperLumina DIN 5 to RCA, and a regular Naim DIN 4 to RCA.
I have no idea what I would have used these for!
Maybe something about at some point connecting Rega turntables to the SuperLine (which has RCA inputs)??
If the Din4 is to two RCAs,(L&R) then that could feed a non naim power amp from a HC or SC.
I’ve never tried to use a non-Naim power amp . . . so the mystery continues!
If you can’t remember, I don’t think anyone else will be able to either! I see you are moving to France. That’s very exciting, what bought this on? Whereabouts will you be living?
Ive been meaning to email you! IN Paris . . . planning on spending about 10 months out of every year there . . . to be determined as time goes on. I’ll email you.
This is a fair point ha ha
Or a pair of subs with a low level connection.
A DIN5 to RCA could be to run a non-Naim CDP into a preamp.

Maybe @Bart needs to go back to HiFi Kindergarten for training. He is clearly out of his league…with his own equipment.

@Bart I think you probably used those cables for something with your old 252….which I have owned now for the last seven years.
