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.

@jea48 yes it’s a guesstimate based on my experience with power cords. Except for a Furutech 55n with FI-60 NCF plugs that took over 600hrs (I lost count) on Pass amp to stabilize, all other cables no matter where they were placed took 200-300 tops to settle. I ordered the adapter though as it’s a good tool to have around. and will run this power cable for few days powering the fridge. Just as an experiment as I’ve not used this method to break in power cables.
I don’t want to overthink or complicate this too much for a $50 power cord. I’m just enjoying the music and the moody break in process this cable is going thru. The Aurender N200 the cable is feeding consumes 15w (play) and it’s on repeat round the clock. Fridge should expedite the process so we’ll see.

@immatthewj I have a CD rip of Slowhand and Clapton sounds tired singing on that album and he is definitely struggling a bit there. Sounds like he’s singing with a sore throat on “Next Time You See Her”. 

This is a great thread all from a ground wire question.love the physics and articles.and the debates

I am ordering the adapter.  Another experiment that is quite affordable.

@audphile1  , exactly!  There was a time when I thought that Slow Hand was just poorly recorded or poorly mixed or poorly mastered or poorly whatever, but going back to several posts ago, one magical night it struck me that I was hearing what his voice sounded like at the time.  As I also typed previously:  in contrast, the guitar work hangs in the air in front of me and Marcy Levy's voice sounds great.

 

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. 

@blisshifi  , I do not think that aspect was ever mentioned until now.

@mark200mph  , welcome to the A'gon forums!  (And this particular thread never even got ugly.)

No doubt many of us have ears/brains and systems that allow us to hear these changes/differences. I cannot even go as far as saying improvements, because this is dependent on each of us individually. But, folks like crf, who claims to hear no differences, is still sad to me. The list that @audphile1 came up with why this is so, is quite on the money. Using Clapton as the example here, over the years, his voice has changed, and his guitar virtuosity has changed. A great system exposes this, and to me is one on the wonderful aspects of listening. I listen to Clapton because of his guitar playing, and his voice. I do not sit there analyzing his health conditions during the making of a particular recording. However I will say, there are other recordings of Clapton I listen to more than Slowhand (a bit countryesh imo), as I agree, he was likely struggling a bit during that time (when I saw him at the Garden that time I mentioned above, he was "out of it"). Sad really. The same can be said for any other musicians of your choice. Sinatra, from the earliest days to his latest, sounds different, but he maintained his phrasing for the majority throughout. When a recording is made, it is generally a testament that the artists are "at their best". A great system (as with my system) allows "everything" to be heard. I hear every manipulation being created by the engineers/mixing folks; the equalization, the compression, and the timing, synchronizing the individual tracks to form one performance. This, to me, is the greatest achievement during the recording process, and this is why, I can appreciate listening to a studio recording and hear "a performance". I however simply focus on the "musicianship", not the tinny treble, the bloated bass or the added reverb, of a particular recording. These are the reasons too many folks only listen to the better "sounding" recordings, and this too is sad. Listening to Cream, Blind Faith, and his earlier works with the Yardbirds and the Bluesbreakers, my system and I, are as one ! I am listening "to their playing". If people can learn to do this (yes, I said learn), much money can be saved in the long run. These are recordings, people. There is vital information not being enjoyed by many of you. Here I go again....my "musicianship" rant. So sorry. My best, MrD.

Of course, recordings such as Bill Frisell’s East West, which is all live tracks, might not need that synchronization, but it is apparent that eq and other studio things were still incorporated .....but, the musicianship....is GREAT. BTW, normally I would be at the community pool, but it is being re surfaced now. 99 degrees in CF, and the pool in not accessible. BS I tell you! My ex is enjoying the pool I built us, along with the house I built us. Life goes on. Enjoy!
