Do power cords make a difference?

will they increase the performance of a powered sub? is there a way to convert a receiver to use a detachable?

Most of the newer mid level and up receivers usually have detachable power cords.

You would need to install a custom IEC socket and solder on the leads of the original, captive power cord. I've done it a few times, and it's pretty easy if you can do that chassis/cabinet work.

i bought an older model brand new yamaha765 and a used hk 3490, neither have a detachable, thats a far off mod, just curious was all, still curious about the subs

Does the PSW 505 NOT have a detachable cord? I've never looked at the back of one. I'm pretty sure the 110 does NOT!

seabeerob213

they both have them, just curious if buying a good cord would be a benefit, the 505 has IEC style and the 110 has the kind that looks like a sideways 8

i have the dual voltage european verion of the 110

I’ve never heard a difference in power cords and really don’t see how it would be possible. The way I look at is as long as the power cord is no worse than the cheap Home Depot builder’s grade crap wire that’s in the wall then I’ve done as well as I can.

Not trying to sound rude, but it sounds like you are doing as well as you can hear and conceptualize. Can you conceed that there may be differences that you are not hearing (due to your gear, possibly?) and that you are not aware of all possibilities how and why a power cable can make an audible difference?

You could be right, it may just be me. It’s true I’m not aware of the possibilities of how a power cord can improve the sound of a stereo system. I can only call them the way I see (hear) them and I haven’t heard an improvement in sound with various power cords. Point well taken, it could just be my equipment.

If a power cord was to make a difference it would only be if it was up line from the Power Conditioner.
Otherwise the wires in the wall and the outlet and the brakers in the service box would be a problem also along with the power wires coming from the main source , the power company.

I'm not sure how it works, but I'm in the middle of discovering the differences (yet again).

We recently move my father-in-law in with us and my man cave was remodelled into his inlaw suite.

I'd temporarily moved various parts of my various systems from room to room, not paying as much attention to details.

Then around Thanksgiving I started rebuilding piece by piece in the living room. I guess I'm cursed because I've found I really can hear the difference between power supplies, cables, wires, components and tubes. I'm very comfortable sinking good money into power conditioning and power cables based upon the return I get in listening pleasure.

P.S.: Enders, just saw your PM and will call you tonight

Why do you feel you need to destroy outlander's open-minded view which I found refreshing for a change.

You really should not post if you do not know what you are talking about. Last week I had a dedicated 20 amp circuit added for my two channel system. The improvement was immediate and obvious. Quieter background and more detailed bass being the first things that jumped out. Before I had the circuit installed I upgraded the power cords on each piece of gear. Every PC upgrade made an obvious improvement. Like it or not, power cables, and every other cable, matters.

Indeed.

Well I have an opinion too, the reason everybody does drive the same car, live in the same house, and work the same job. Besides you did add a new circuit so at least you got as far back as the breaker box which was my point anyway. There is no telling what kind of wiring that I have behind these walls :cheesygrin:

I removed my power cord completely and noticed an immediate reduction in all background noise. No EMI...no RFI...absolute and utter silence.

But now I need help trying to figure out why my music won't play.

If that were true that power cables make a difference then would it not be in the Audio worlds best interest, makers of Pioneer Elite, for instance to make a detachable power cord?
I mean if it's going to make their AMP SHINE and make customers go OHH AHH listen to that difference that power cable makes..
Then why does PIONEER ELITE not give you the detachable cable option..
Or better yet why don't companies give it to you, and if you say cost well come on over, do you really think a power cable is capable of costing more than a highend AMP..lol
Please guys just look at all the evidence about HOW highend wire got started in the first place..
Back in the day they started to dress up the wire to make it look nice because people started asking why does the speaker wire look like crap, so they dressed it up and then realized hey we can make a fortune selling this crap..
BUT hey if your RICH buy me one too because I would love to selll it and buy a car..

If I was where your at I wouldn't bother/worry with/about cables anyway.



You have it figured out!!

Enjoy!!

Check out ANY conductor resistance calculator...hell experiment yourself and see that different conductor/core/quality materials will make a substantial difference in how much resistance there is along the signal path.
This also effects EMI, RFI, etc along the length of the wire.

To say otherwise shows how little electronic theory you have knowledge of.

Will it make an "OOOOOOHHHHHH AHHHHHHHHHHH" night and day difference? Nope. And I haven't read anyone claiming that either.
Will it, at a certain quality level of equipment, make a noticeable and audible difference? Abso-farking-lutely it will. Once you reach a certain point in this hobby, changes reach a level of "diminishing returns" where you have to make BIG changes to see a minor difference. But having the highest quality cables is going to change the way things sound at that level.

Jhayman

Sure there can be differences like you discribe but will it make an AUDIBLE difference NO..
only Measurable not AUDIBLE..
Like I said if power cords make a difference why would a HIGH END Reciever like the Pioneer ELITE, give it's buyers the choice to buy an after market power cable if it makes such a big difference??
You would think Pioneer would want their customer to have the best sound possible..
I'm still sticky by what I have read, wire rarely makes a difference only in long runs, if YOU can hear a difference then maybe SUPERMAN is your buddy, lol

Thats NICE and classy..

Your certainly entitled to your opinion, but obviously you don't know if they do or not as you have zero experience. In your own words, "what you read" is very telling. Everything has to meet a price point dude. Polk wants their customers to have the best experience too, doesn't mean they can put all top quality parts in their speakers though.

tonyb

I'll say it again....audio is played on many levels. Because your not at a certain level doesn't negate the ones above you, nor the ones below for that matter. Audio is enjoyed at many different levels, to poo-poo others is simply dumb imho. If your happy with what you have, cool, rock it. If you seek further improvement, many here can help you achieve that too.

You really won't get the full warmth out of your new set of power cables until you've replaced the wiring in your home from the room to the power junction box. I used a pure silver 12 gauge set for mine with a ceramic insulation. The whole thing had to be fabricated on site.

I'm not sure what to do about the transmission line from the power station to our home yet. I'm concerned about interference from birds sitting on the power line.

20hz

mostely on your wallet
But if you do the job 100% like sodablue said I am sure there is a audible differance .
I talked to a friend that spent a bunch on both he found a biggersound improvement replacing his rca cables w/high end than the sound differabce when he replaced his power cables

tonyb

As usual.....

Those that don't know......just don't know.

Now I would think (and I know I shouldn't:razz:) that a line conditioner used for extremely expensive medical equipment would be on the order here if you really want to get down with this.
Something like this?
