What's the benefit of balanced tonearm cables?

I've never heard of blanced cabled cancelling cable artifacts. What they DO measurably do is reject common mode noise.  EMI/RFI is often like that.  It induces a current in the same direction in both conductors which cancel each other out.

They may also have increased capacitance or inductance as a result of the construction.

For a tonearm, it's very interesting, since most cartridges are inherently balanced, using a balanced input stage could lead to less noise pick up, and better detail retreival.  COULD. No idea if true.

Balanced signals have greatly reduced common mode noise, but that’s not what I would call a cable artifact, so much as atmospheric, or environmental.

What they can completely eliminate is ground loop contamination, and crosstalk.  Cross talk COULD Be caused by a non-zero ohm ground.

So three things:

• Improved common-mode noise rejection
• Eliminated ground loop
  
• Reduced L to R cross talk
  

But eliminate cable effects? That’s a bit of a stretch for me. It does not cancel out capacitance, inductance or resistance. 



Best,
