Pioneer PL630- upgrading the phono cable?

No- this is more of a purist's question regarding the ability for me to perceive an audible difference if I replace the 44 year old OEM cable with a higher end aftermarket phono cable that offers better RF insulation, lower capacitance, and SUPPOSEDLY a more transparent sound to the preamp. 

For clarity, I replaced my Shure V-15 Type IV moving magnet cartridge with a much better Audio Quest Moving Coil cartridge.

To all, thank you for your insights- I have elected to leave the OEM cable in place and listen to the cartridge when I receive it this weekend. It is a rebuit Audioquest 404B which was commissioned and made by made by Scantech (later renamed to Lyra). I am told that the generator in this cartridge is the same as a Hana Umami, which is why I even mentioned that as an aside.

It is my understanding from reviewing the history of Audio Quest that they commissioned Scantech to make their very first MC cartridge - model AQ404B in 1982. It is good to learn that Excel had a role in later AQ models- thank you!

It is great- I am not sure my 70 year old ear could discern the difference in an upgraded audio cable- LOL!
