I would be inclined to put a small dab of clear silicone on that spot to seal it from further degradation.
Nordost cable damage - opinions?
I bought a pair of second hand Nordost Frey 2 speaker cables but the seller did not specify that there was a bit of damage to one of the strands in one cable
The silver is stripped at that point revealing the copper, and there’s likely some damage to the copper underneath also. The sound does not sound flawed in that there’s no obvious noise or anomalies, but at the same time I don’t know if it’s performing as well as it should be.
