Hi all.

 

I have two Audioquest cables, one Diamond, one Vodka. Both connectors on both cables dissolved (the plastic bit at the end carrying the conductors simply broke off). Attached is a photo showing how it looks like. 

 

Same thing happened with a friend that is using totally different setup with different electronics. 

 

And as you might guess, having paid so much money, I took very good care of them physically. 

 

Audioquest says they never faced something like this, so it should be our equipment causing the problem. (dCS Network Bridge in my case and Upsampler for my friend) we are using SOTM  CAT7 as replacement and other places in the system with the same connectors so far without a problem. 

 

I wonder if anyone else had a similar issue with Audioquest or is it really something specific to our cables/system? 

 

Cheers

 

Kunter

I have one vodka and one diamond, I think about one or two years, whit any issue. It seems to me a real strange beahviour, no usual. Has you used something to clean the contact? I cannot suppose other cause of this phenomenon apart to  use aggressive cleaner

picture looks more like the plastic latch broke off, your connections still appear to be there. Data centers use tie downs to protect against this, can happen when you are moving cables around

Plastics can become brittle under influence of time, sunshine, heat and solvents. It depents a lot on the choosen plastic and it's ingrediënts. The supplier should choose a suitable plastic that is up to the task.

 I used couple of cleaners over time, Caig Deoxit and Stabilant 22. Can they have such an effect?

In case the broken plastic parts can be easily broken into smaller parts or if the surface is a little white(ish) I think the deoxidising lubricant could de well be the cause. But I would not have thought this likely before hand.

Are you guys running Power over Ethernet (PoE)?

My thought exactly. However, I very much doubt dCS would be sensitive to that creating a current draw...

I have NEVER seen something like this on any connector I have ever used.  This is not the answer.

Not only better photos of male cable termination.  Female of equipment as well.

 

Hard to imagine no damage to the latter.  Without professional examination of both the chance of inconclusive answers are more likely.  At least it appears neither of you lost the hardware they were plugged into outright from the incidents.

Yeah. From pics of the cables on the internet, it looks like the contact portion fused to the female ethernet port in the device and broke off! Very bizarre. Unlikely you will be able to plug another cable in that port.

The more I look at this the more "mechanical" it seems to me. I wonder if the choice of ethernet jack in the dCS is making this particular cable get snagged and break off?

Yet it appears another cable was substituted and has passable functionality (at least during the initial minutes testing is likely to occur in)!

 

You might be better placed to comment whether software could be used to test this connection at home.  Or if the manufacturer is holding a proprietary key forbidding consumer access.

I have no such issue in my Rossini, but I don't use this cable.

I think it is not an issue with the cable but wrong usage of contact cleaner on my part. Years of usage and repeated application should have caused this issue. Stabilant has a very good performance so I may have overdone it.

 

Thank you all for chipping in...

I can definitely imagine a chemical making a particular type of plastic soft and sticky and having this as a result. Make sure you didn't destroy the ethernet jack on the dCS device.

Stabilant is pretty non reactive unless the alcohol is doing this. I'd suspect the cleaner more than Stabilant at first blush.

This sounds like melted connection accepted a new cable.

Some cables are made with plasticizers, which are a petroleum industry byproduct, utilized to make the wire insulation flexible. Anyway, the plasticizers can leak at the ends and corrode certain plastics. The only simple way to tell if this is happening is to look for an oily residue at the connectors?
