You won't hear a difference. Seriously.
Almost all cables are shielded, but the IXOS brand had absolutely nothing to shield the ones I bought with list price of $400, but they were noise free, so the customer decided it wasn't worth the headache of returning them. Those had no-name plugs and three braided wires that could have been from extension cords (Black, White & Green) with translucent white plastic braid covering the wires.
I have used Mogami, Hosa, Canare/Neutrik, Belden with Neutrik and other brands of plugs and none of it improved or degraded the sound. My old Audio Technica mic cables work just as well as any of the more expensive ones.
I know people who work in consumer, pro audio and recording studios- one of these guys works in all three and when I asked him what he thinks of the high priced stuff, he asked "Where do you think studios send people on a Friday night when they need cables and adapters?" I answered with 'Radio Shack" and he said "EXACTLY!".
Don't sweat the cost, enjoy your system but if you do buy some expensive AND cheap ones that can be returned, do your own comparison, but do it right- knowing which is being used DOES affect our judgement.
