A stupid question(s) about power cords


As the title indicates, I admit that this is probably a stupid question. But since I don’t know (for sure) the answer, I am asking it anyway.

The recent power cord thread got me interested in a power cord upgrade (from the stock cord) on my Maranzt SA10 (SACDP). The power cord receptacle on that particular component does not have a male equipment ground pin--only the neutral and hot pins. Therefore the cord supplied by Maranzt is a two pole (if that is the right terminology) cord. But because I have done it this way before, I do know that it will accept a power cord with an equipment ground as well as a neutral and hot.

Question 1: I went to musicdirect and looked at some power cords and I saw one (an open box Audioquest NRG Z2) that they were calling a two pole cord. The end that plugs in to the component only has a neutral and a hot, but the other end, the end that plugs into the outlet in the wall, does have an equipment ground blade (so that end has three blades). Why would that be?

Question 2: (and this is the stupid one) if a power cord has an equipment ground pin plugged into the wall, even if it is not plugged into an eqipment ground in the component itself, that cord is still connected to the neutral bus bar in the panel, right? So that being the case, since the equipment ground wire in the cord is right next to the hot wire, is there a way unwanted stuff (rf or whatever, my understanding of this is quite limited) can that dirty up the power that is traveling on the hot wire  in the power cord?

I think that the answer to the last question is probably going to be ’no’? And if the answer is ’no’, that means that I really don’t need to shop for only two pole cords, right? And I see this as sort of important because if I buy a two pole cord, the ONLY component I can use it on/try it out on will be my SACDP--there will be no playing around with a two pole cord on my preamp or my amp.

And ALSO, if I don’t feel constrained to shopping ONLY for two pole cords, I would probably have more options to consider.

TIA for legitimate insight to this, and to all others, feel free to ridicule me and my question--I don’t mind.

No spinning discs required. Just keep the player on. Or connect a laptop (or iPad) to it and stream YouTube playlists or Qobuz, Tidal whatever via usb while not listening to CDs. SA-10 has a USB input and is pretty decent used as a DAC. If it goes into standby due to inactivity with CD this will keep it on. There are ways to keep the SA-10 on and consuming power. No one said anything about spinning a disc 24/7. 

I am of the impression that if a piece of equipment is connected to a new PC and at least turned on or on "standby" it will also achieve "credit" for burn in hours. It doesn't necessarily have to be playing music? I have a new power cord attached to my power distributor and am leaving for 2 weeks, my thoughts were if a few things connected to the power distributor (Shunyata) are in standby mode will help burn in the PC connected to the Shunyata?

I only read the first page of this thread, so apologies if this was already covered.

In addition to connecting the chassis and any required internal components to ground (if it is inherent by the component’s design), the ground pin of a power cable is often used to ground the shielding of the cable itself, which reduces noise and helps to address EMI. So you may find that using a high quality 3-prong AC cable on a 2-prong unit to be superior to other high end 2-prong cables.
