Hi,
Does anyone know why the Hi-Line has a small resistor in side?
If I use non-Naim inter connect eg:RCA ,
will it affect the design voltage/ resistance/ impedance…? thanks
Ken
According to Naim the resistor in the Hi-Line and Super Lumina interconnects is there to “control the characteristic of the screen “seen” by the ground.”

The “ordinary” 5 to 5 pin din Naim interconnects (eg the one in the box when you buy an ndx2) do not contain resistors. So you can use any interconnect you prefer without issue.

Thank you both for the information
Perhaps there is a clue here - as to why some non-Naim I/C’s may sound different, with Naim units…?
Has anyone got a multimeter and could measure the resistance value, just out of interest?
In the SL IC, its 470 ohms if I read the colours correctly.
Its connecting -ve with the coax outer.
Ah, quite non-trivial, then. Another reason different interconnects sound different!
I wouldn’t call it “non-trivial”, its just a shunt connection off -ve to the floating coax screen.
Its not part of the direct the signal circuit as such , but it might potentially cause a small change in capacitance, so maybe … ?.

I was just thinking if that is the secret “recipe” to sell Highline, SL
As it add back the required component for it to sound its best?
Could be a marketing thing or worst?
Not really. I don’t think Naim made much if any mention it with the Hi-line. If it didn’t make a positive difference to performance then Naim would not have bothered with it.

A separate question.
Anyone know the Hi-Line or SL (DIN -RCA ) version, is the RCA connector 75ohm?
Or does that matter for analogue use?
Thinking to butcher one (DIN-DIN) version and convert to a WBT RCA for headphone amp.
Don’t do it! Better to trade the DIN-DIN for a properly configured DIN-RCA.
