This is are very stiff cable but making a interconnect with it is certainly worth it.
The conductors are double insulated so after the first layer there is a ptfe layer so be aware of that.
The outer sleeve is also made of two layers of witch one can be peeled of if you are careful not to cut too deep this makes smaller cable entrance diameter RCA plugs possible to fit.
Compared to a expensive silver cable it loses some fine nuances but gains in solidity and warmth it is not a"warm" cable but very neutral and resolving.
