Because I record so much content on a weekly basis I find myself recording at least 20 hours using OTA. Being the nosy person I am I can't help but compare OTA vs "E" PQ. Comparing nightly broadcasts like NCIS, Bones, Vampire Diaries, Blue Bloods, Castle, as well as NFL games on ESPN, CBS, and FOX, baseball games on FSNAZ and PAC-12 Channel, boxing on HBO and ESPN 2, I see no noticeable differences between OTA and "E". I really expected to and actually was hoping I would. I've asked my wife many times for her opinion and she agrees with me. Sony 60A3000.
