chord signature interconnect hum

Cold solder on one of the pins? Just return the cable and have it exchanged.

I noticed this with a Chord Shawline RCA to XLR and discovered it was due to the cable touching or close to a power cable, obviously a lack of adequate shielding. Sold it for a custom Mogami cable and had no such issues. Given the cost of such cables you expect better.

Is the hum equal on both channels? If not, swap red with black (or whatever) at both ends of the cable and see if it changes.

if hum/buzz is predominently one channel and swaps over with the cable, then the cable is faulty (which as suggested above could be a solder dry joint).

If predominently one channel and doesn’t swap over it’ll take more thought, as you’ve already shown with another cable that the source output and amp input appear to be OK.

If equal or near equal both channels it is unlikely to be a cable fault as such, but maybe it is a cable more susceptible to induced hum from mains wiring than others. Try having the amp turned up enough to clearly hear the hum when you are bent over the equipment (but not a very high volume in case the following suggestion causes a plug to pull out), and move the cable around to see if the hum changes - proximity to mains cables and transformers in particular could be significant. if it does, then this cause is confirmed, and if you can’t find permanent positions for the cable and/or interfering source that reduce the hum to insignificant (to you), then the only solution would be to change the cable for one with good hum rejection.

hello,

Thanks for the replys, the hum is on both channels, i also have a chord signature rca to din connected to my anthem AV receiver. This cable also hums but a little less. I have tried moving cables away from mains cables but the hum is still there. It starts at 12.00 on the volume and is very audable at maximum level where as the naim cable is almost silent. No point in me sending the cables back as they are made this way. in actual listening levels ten to twelve i dont hear any hum so i guess its normal for this cable and  I cant fault the music  using these expensive cables.

Yes, if inaudible at the highest level at which you listen then clearly the hum is of no significance and not worth dwelling on.

AFAIK Chord offer a "lifetime" warranty covering defective materials or workmanship, so if you think there's a problem with your cable, I'd return it to your dealer and they can send it back for repair. It certainly shouldn't be down to inadequate shielding as that's one of the key considerations of Chord's design approach.

hello,

I cant see how i would have 2 faulty chord signature cables. i would like results from other members if they have the same cable.

I have one Signature and one Sarum. And they don’t hum or buzz. 

So by the looks of it - either your particular cable or mor likely an issue within your setup. 

Noticed one point: hum in your AV setup. There shouldn’t be one, irrespective of the volume. 

Perhaps a ground loop after all?

Otherwise, as previously noted, if inaudible at listening position at a volume setting equating to your highest listening level, why worry about it?
