RCA Phono Interconnect Identification

[Redox]

Hello everyone, I have just come across this pair of interconnects, they appear to be very good quality but I can't find any identification markings.
Does anyone recognise these?

No.

Possibly Audioquest from the 1990s?

Thanks for the input, they do look like Audioquest Ruby cables.

:-)

I agree they do look like Audioquest Ruby cables.

But if they are, they must be very old versions. All Audioquest cables I have seen are not only marked as such on the cable's outer sheath, they also have the name marked around the outer conductor of the plug where it mates with the phono socket.

Also the plugs on all Audioquest cables I have seen are a gold colour (gold plated?), whereas yours look to be nickel plated.

Regardless of their provenance, if you are happy with them, then continue to use them. :)

I've got some Turquoise I bought back in about '97, plugs look identical but obvs the cable sheath on mine is blue.

I bet it's all the same wire underneath.

Is there any writing on the cable? I agree the pattern of the knurling is the same, as is the screw fixing, but we're your's nickel plated?

Not sure just went to look for them and they're not in my cable graveyard so I don't know where they are.

They have directional arrows on them, not sure about any writing.

If you use Google lens to search for them, several suggestions are made, including Audio Technica, Burmester & Cardas.

I would say that the directional arrows are a carry over from professional installations where long cables need to be identified as to which end the source is.
I can't see the point of there use in a 1 metre RCA phono interconnect.

[Barry]

The only time a cable is 'directional' is when it is used in a so-called semi-balanced configuration. Such cables use two conductors for the signal, and the separate screening/shield is connected to the same conductor that is used for the outer part of the phono plug. The connection to the screen is only made at one end, and this end is plugged into the source. The arrows are there to show which end is which.

It's so they don't have dozens of punters calling them every day asking which way round they should go.

Is my theory.
