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.

@immatthewj just sold SA10 few months ago. Nordost Heimdall 2 was a nice match with it. Opened up the top end a bit and improved clarity. Give it a shot. |
@immatthewj yep regular 15A IEC plug. Works fine with SA10. And yes sorry not a fan but I think it was more of a synergy and preference since the SA10 gets consistently good reviews. I just didn’t like it in my system. |
There are reasons why some don’t hear difference between cables. 1. Low quality components 2. Bad room acoustics even with decent components this will be detrimental 3. Bad setup - speakers are not properly placed, speakers blocked by large furniture, no designated listening position, no critical listening and again low quality components and room acoustics 4. Listener is not able to hear differences - not everyone can. 6. Doesn’t want to or doesn’t have the means to upgrade cables In any case, arguing with these people is pointless.

@immatthewj it’s all about trying the power cord upgrade for yourself. Some power cords result in very minor changes, some produce a difference big enough to go wow. One such example for me was the Nordost Brahma power cable that I tried on Rogue RP-1 preamp that I had at the time. The difference was huge. Bigger improvement than rolling tubes or changing interconnects. |
@immatthewj it’s definitely very possible. |
@asvjerry this happens frequently. I won’t deny it. But then again it happens to us because we hear the difference and we want to hear what some other power cord or interconnect will sound like. Not the best situation to be in because it almost always means you’re switching to analytical listening looking for changes. Worst part about it is when some of us enter that mode it is extremely difficult to get out of. Guilty as charged here. I hate when it happens because instead of enjoying the music I’m comparing what row the mosquito farted in with cable A vs cable B. Was the mosquito better defined when he farted with one cable or component over the other? Was the mosquito fart texture better with one cable vs another? If you hit a bullseye with synergy with your new cable or component, good chance you’re back to listening to music as opposed to listening to sounds much sooner. But it doesn’t always work this way. You get on a merry go round looking for your next upgrade. Sooner or later… |
@immatthewj I would put my best cord on the amp first and try it there for a few days. Then return to stock on the amp and listen to few of the same tracks. Then introduce the upgraded cord on digital and determine where it performs best. |
Yes the default sounded best to me as well. And if I’m not mistaken when you play an SACD the filter selection is disabled. I didn’t like the other filters and dither options as they just didn’t sound right to me. |
