the combination of DIN on one end (maybe, depends) and shielding (as noted by Chakster) is the answer. Phono outputs are tiny and therefore pick up noise easily since they are amplified greatly before they go into the regular preamp (line) stage. Almost anything benefits from a Faraday shield, but its most useful when the signal is tiny.
But this only matters from the tonearm to the phono stage. Once it leaves the phono stage a MC signal will be ~ 100X bigger ( and therefor 100X less susceptible to noise) and MC that figure is ~ 1000X/ Yes, 1000.
The output of your pho stage is, ideally , no different from that of a tuner, CD player or line stage device of your choice. Mostly because it is line stage.
You are not buying a phono cable. You are buying a line level cable.
