Hi Line cable Failure

Inside the black rings there are resistors.

Have you a picture? and if so is at the terminating, or source end or both?

Iā€™ll try and take a pic without it exploding in my handā€¦ :smiley:

Thanks, Iā€™ll also get my ohm meter on one of my spare hilines

Should be easy to measure if so. Why would they want to add a resistor in a signal cable?

Quiteā€¦ I have a spare Hiline DIN to phono ā€¦ Iā€™ll measure after breakfastā€¦ they could also be capacitors or some sort of RFI L pad. Other manufacturers such as DNM do that to help mitigate RF intermodulation in audio components.

No drama, source end - Phew!:blush:



Back together again and back to the gorgeous music it lets throughā€¦ :flushed:

Unless mine is a bodged repair, it has been sent back four times, either way it sounds lovely, much better than the stock cable.

Can anyone here explain the resistor? Iā€™m not sure about the end of the cable, iā€™m not going to go pulling it apart to find out. All plugged back in now and all is well.

I think itā€™s a clever bit of kit but I have vivid recollections of having difficulty in locating the floating pins (with the risk of bending them!), and this is where perhaps the vulnerability of the primary locating lug (as @Stephen_Tate has ā€˜poppedā€™ in his pic) comes in to play. Holding just the main collar can expose this connection.

The above said, my later Hi-Line between S/Cap (Superline) and Pre locates without issue, and appears a tad more robust. Either that or Iā€™m instinctively handling it with more care(?).

Iā€™m probably incorrect here, but in the early days I donā€™t think the collar capping was accurate as to orientation of fitment, hence the struggles?

Thanks, I was hoping to see what it was connected to :nerd_face:

Fell apart again, when I tried to reclip the small arms broke off from that ring leaving me with an interconnect I now need to tape. Iā€™m trying with masking tape. We will see how it sounds. It always sounds off when I have removed it and it takes a while for it to get back on song. Bummer it broke though.

Yes it does sound very, very good.

Yes of course. The resistor leg-ends appear to have heat-shrink over the solder joints, therefore itā€™s quite difficult to peer inside and see where things are actually connected without properly taking the whole plug apart. :grimacing:

@Simon-in-Suffolk does that pic help?

I do wonder why Naim havenā€™t brought out a Mk2 version with maybe aluminium collars as opposed to the plastic ones. Is performance impacted that much if they do? Who knows? Seems ok for the SuperLumina version thoughā€¦

Yes, so I measured the cable and there was no measurable resistance, everything checked out at about 0.1 ohms ā€¦ but the picture suggests one end of the component is connected to the shield in the cable, so could be a shield leakage resistor to ground.

I believe a shield normally adds capacitance. And naim seems to not like high capacitance. Could this be a way of reducing it?

Two failures here in 12 years. Both replaced free of charge but I wasnā€™t sad to see the back of it when I moved to non-Naim streaming. Quite telling that we have this and the Burndy discussion going simultaneously. Notdiscussions you see with cables from elsewhere.

If Iā€™ve understood the restistor connections correctly (from a photo) its linking the screens to -ve.
A screen will add capacitane thru its proximity to the signal conductors, but this will be a very small number.
