@holmz I think your query has been on how to exchange parts belonging to the Box, especially the wire.
I have suggested a method that can bypass the wire, or to use a wire of a particular type.
Both of these can produce the configuration the box offers and both configurations are available in the Market Place.
As said reducing the amount of connections is most desirable.
There is an advantage to the Box, as there are not a broad selection of DIN>RCA Cables as their are RCA>RCA Cables.
This box will enable the opportunity to experience a broad range of cables over a period of time and assist in your experiencing Cables as an umbilical down stream from your Analogue Source.
This is how others who I have introduced my cable suggestions to have discovered its value in their systems.
This is now why in these systems there are at present produced Tonearms with PC Triple C now used as internal wiring.
DIN>RCA PC Triple C Cables purchased and a Phonostage had the internal signal path wiring exchanged to the same material.
Contempt prior to investigation is a very restrictive place to be.
There is nothing like being curious and inquisitive, it is a great place to be, no matter what the outcome of the experiences undertaken, for others the healthy disposition has proved to be the mother of invention.
Alternatively there are other suggestions being offered, that from some will potentially end up with you being informed of needing dump your equipment and spend thousands $$$$$, always easy when it is others money.
