Irony meter off scale - you invented the above scenario with coax, Steve was confining his statements to only twisted and paralleled pairs

In any case, balanced operation is next to useless, unless you are in a high interference environment when it comes to phono operation. So let us continue on single ended operation.

Have you decided on the input Opamp ?

And this is just the sort of thing one would come up with who had little more than a sixth grade science class understanding of conduction in metals.

Amazing how things sound better even though reason given for it is so off base.

Mm, you sure Frank Blöhbaum didn't buy up all Deutsche Post triode + pentode valves ?

Joachim, the exact IC op amp is not necessary to define at this moment. Just low noise type.

The real problem is, because they are traveling so fast, the electrons fly off the ends of the traces because they are unable to make that sharp turn.

So, dou you think it is a good idea to make the feedback resistors the same impedance as the impedance of the cart. ? Whould not be the lowest noise though, and the cart, being low impedance whould not provoke common distortion much anyway.
