Is tonearm cable the most important cable in the system ?


Opinions ?
In the case of my Nottingham it goes from the cartridge right into the phono. It is not shielded, I guess, and there is nothing I can do to improve it. Not that it is bad, I think it's quite good.

I find my tonearm cable to be very sensitive to magnetic fields and it's the stock cable that comes with the Technics SL-1210M5G.  I have not upgraded this cable as it is decent.
There is no "most important cable" in anyone's system.  Every cable in your system contributes to the resultant sound.  If you doubt that, take a quality cable you currently use and replace it with the stock throw- away cables that come free in the box.  That I do believe will settle the matter.
The cable is much less critical if you can run it balanced into a balanced, differential phono preamplifier.
