Having low phono cable capacitance is important with MM cartridges, but it's not likely to be an issue with MC, unless perhaps you're using some odd cable. As for RF, you may get better results by using a shielded cable, but on the other hand you may not - the only way to know is to try.
Pioneer PL630- upgrading the phono cable?
I have a Pioneer PL630 with an upgraded Audio Quest 404B (essentially a Hana Umami Red) Moving Coil cartridge. I still have the OEM phono cable and am considering replacing it with a higher end cable /ground to reduce RF interference and to lower capacitance, and provide the best possible signal to my Rega Aria preamp. Has anyone done this with their turntable (any higher end turntable) and does it provide a noticeable sonic improvement?
