My experiences has shown that D.U.C.C Wire used in a Cable from a Company such as Acrolink Leggenda can offer a influence toward the description of a Sonic Signature you have pointed toward.
This Cable is supplied either with Plug Connectors or without, it is offered with different configurations for the Wire and Sheathing at different pricing per metre length.
Using the method where there is not a home trial period offered, and buying it as a Cable Only, and using recommended Plug Connectors will allow for a very high quality Cable to be produced at a reasonable outlay.
