Are Expensive Balanced Interconnects Necessary?

I do believe that cables matter. I want to put more money into my phono amplifier and spend more on my RCAs from the turntable (Technics 1200G/Hana ML) and less on the XLR phono preamp to preamp.

Looking to pickup Esoteric E-02 Balanced and have McIntosh MA12000/Sabrina X/REL S812.

So, I gather that the answer to the original question is definitely maybe, or certainly could be.
