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.

The only power cord you ever need for your CDP is the stock cord that came with the unit. I'm an electrical engineer who knows a thing or two about cable electronics. If you want some thick substantial power cable go buy a 10 awg cable on Amazon for $30 will certainly please your eyes and make you feel good. These cable resellers aka major brands sell those cables adding 10x or even 50x profit and the price tag has absolutely nothing to do with improving the s.q. of an audio equipment. And do not pay attention to the trolls on this forum they are here to mislead you to spend thousands of dollars on so called major brand cables. Hoping you're not one of them.

@classicrockfan , Matt is breaking in some Amazon 10 gauge power cables I had recommended to him (x3, for cd player, preamp and amp). I generally respect engineers, but not when they say power cables do not make a difference, over the cheap included cords. Have you tried a $50 2meter cable off Amazon and used your ears? Why do they sound different? Why do fuses sound different? Why does copper sound different than rhodium? Equipment break in? Don't believe in that either? With many of us here (I feel comfortable grouping us golden eared listeners together) who actually listen and have systems capable of us hearing differences/improvements, I am truly sorry you feel the way you do. Enjoy your factory cables. Always, MrD.

@mrdecibel 

Yes i have. Probably the same 10awg power cables I bought off Amazon priced between 30 and 50 depending on the length. I like them a lot because they make me feel very good looking at these beautiful power cables not that they make an audible difference 

Why do fuses sound different? Why does copper sound different than rhodium? Equipment break in?

Why do some people believe 1+1=3?

CDP... Maybe will burned-in in a year or two, if ever.

serious question, not intended to come off as sarcasm: then would the OEM power cords that come stock with CDPs take quite a while (a year ot two?) to burn in? And I assume that is because a CDP does not take a gob of amps? I could certainly order that adapter and run my refrigerator from that cable for a while . . . that would not be a problem.

To my ears it sounds like a blanket thrown over the speakers

As far as Slow Hand, I am not using any of my CDs for A/Bs yet, I am just going through my red books (saving the SACDS for later) and playing a lot of stuff I haven’t listened to for some time as the speaker break in and power cord burn in process. It’s actually kind of interesting to hear those CDs I haven’t spent time with for a while. I pulled Slow Hand out to the ’To Be Played’ section after that last short interchange with @mrdecibel .

It reads as if you find Slow Hand to sound somewhat muffled? If I am not putting words in your mouth? I found it that way myself for quite a while. (I remember I bought that 8-track when I was in the Air Force back in ’79, and at parties we’d crank up Clapton’s cover of Cocaine on someone’s rack system, and we loved it back then.) Then back in maybe ’94 or ’95 or ’96 or so after I started putting together a better system and started buying "audiophile CDs", I picked up the MFSL red book of Slow Hand, but I still didn’t find it a sonic gem. I had my system hibernating from around ’08 to late in ’17, but sometime after I woke it back up, I started listening to that MFSL remaster of Slow Hand, and I found the guitar work to float in front of me and actually sound pristine. The more I listened to Clapton’s vocals the more I started to think that it wasn’t the mastering or the recording that was making the vocal part of the recording sound rough, I started to think that it was that his voice was in bad shape at the time and I was confusing muffled with nasal. So after this short discussion Dan and I had a bit ago, I did some googles on Eric Clapton, and it appears as if after getting off of heroin he was drinking like a fish and doing (I assume snorting) a lot of coke. (And this was when he was recording Slow Hand.) I bet he was smoking a lot of cigarettes as well. I also noted on that remaster I have, that in contrast to Clapton’s vocals, I thought that Marcy Levy’s backups and accompanying vocals sounded quite good. I can not remember when I had this epiphany, I think it was after I put my SA10 in the system but before I bought the SLP05 (meaning I was still listening to the SLP90) and I will say, that going back a few of my posts, Slow Hand does not always strike in quite the same way, but I no longer hear it as sounding as if, as you put it, blankets have been thrown over the speakers. Going back to that post I made about this personal phenomena, @audphile1 suggested that the power coming into my house is better on some nights than others, and I am willing to consider that as possible, although I always used to attribute is to my ears being bipolar.

Oh well . . . as I have typed before and I am sure I will again: Ramble On.
