naim 5 pin Din to 4 RCA connection thoughts

Hi I am looking to replace some short cable with longer RCA to 5 pin din connection for analogue in on a naim AV system. with 4 RCA’s to the 5 pin din as all the -ves end up at one din pin is there any advantage of keeping the -ves seperate for a full 2m, I am thinking of using a 12 AG lead from the earth pin to say 1.75m and joining the 4 RCA -ves there rather than further down.

Also unsure which end to earth and shield. I have some Belden 8412, sharkwire but thinking about Dueland 16GA as an option any thoughts appreciated

My current thinking is 4 dueland 16GA cables from the positive RCA to the pins, then using a short length 0.25m say to take the individual RCA -ves and then used on thicker cable perhaps 12AG to the earth pin (I know I will need to taper the cable to solder at the pins) then use a separate shield over the whole cable and terminate this at the .25m point ?

So it should be normal RCA configuration for the first .25m then just 5 lines to the pins at the plug from that point

Anyone used Dueland cable with naim ?
 
Oh dear, NAIM isn't compatible with my Pioneer amp & Tapedeck DIN.



DIN sounds better than RCA ?? Ok, If NAIM needs 50 Ohm impedance, use coaxial RG58 RF cable & connectors, not DIN.

I understand the connections, I have made many its construction design alternatives for earthing I am interested in they will ofcourse work either way but which is better
