The MA ones aren't just "power cords", they are shielded and the conductors are twisted and throw off much less RF than normal power cords. I saw a test with an RF meter and romex, standard IEC power cord, bare 14/2 conductors, bare 14/2 inside metal conduit, and Middle Atlantic's "signal safe" power cords. Big difference. Price to match, but hey...you know.
When was the last time you encountered a problem in your system, with interference coming off a power cable? Don't get me wrong, I 'think' I have seen it before. But in 25+ years I have only thought I have seen it a few times (pretty sure it was defective equipment causing it anyway). It is so rare that I would never bother getting anything beyond standard power cables (at the correct gauge for the application).
