Neutral electronics are a farce...

System neutrality is gauged by the percentage sq/signature of your music collection. The higher the quality similarity, the more neutral the system. The more polar, the more skewed the performance characteristics of the components are. How that relates to real life is another topic.

ebm, how do you know your system is neutral?

I think the lesser of similarity among recordings would indicate neutrality as a more neutral system would function as a window into detail…and all recordings differ. 

Wolfman, solid core interconnects are not spiraled. And shielding assuming they have such doesn’t protect against induced magnetic fields, only external RFI/EMI. Hum bucking is not generally employed for transformers although as you suggest it should be. Not to mention that all exposed internal wiring, even the wiring that’s spiraled, capacitors, chips, etc. are subject to the rather large magnetic fields produced by large transformers.

wolf, when the majority fall into a median average with some significantly better and some worse, that is when the system is at the mercy of the recording. When there is no median, that is when some are enhanced by the components, and some are degraded. Experience with multiple systems reveals this.
