"Geez, you really jumped down the guy's throat. Maybe he's a shill, maybe not, but I don't think he deserves abuse." Tom you said this in response to a poast of Elizabeth in the original review of the power cord. but now if I decide to not post a review for reasons you think I might be using then I deserve abuse. Winston doesn't deserve to be abused even if he is a shill but I should be abused for not posting a review.
By the way a component can improve the sound if it performs better then the component it is replacing. If the original component adds distortion to the signal but the new component doesn't then distortion has been removed. Don't take this as abuse, just pointing out some facts.
I will post a review tomorrow. Hope you learn something.

Power cords don't add distortion.
As fate would have it, power cords add quite a lot of distortion, actually noise and distortion, some power cords more than others, but they all do. One of the primary culprits is the distortion produced by the self induced magnetic field produced by current flowing through the cord as it interacts with the AC signal."It looks like the self destruct bottom just blew itself up."

Sorry, Geoff. They don't add distortion. Electrical theory 101.
Spoken like a true music major.
that retort made me chuckle.
No offense to the OP (other poster) intended.

"One of the primary culprits is the distortion produced by the self induced magnetic field produced by current flowing through the cord as it interacts with the AC signal."
Oh please professor, tells us more about this wondrous weirdness... How do it distort?
Just knowing what you are thinking of when you write "AC signal" would help.

Good reaction. Why does the magnetism hurt the sound, grasshopper? For the same reason that the (magnetic) breaker panel door hurts the sound. For the same reason audio transformers hurt the sound. Ain't electricity mysterious?
"Good reaction."
Thanks.
"For the same reason that the (magnetic) breaker panel door hurts the sound."
What? You don't care for the Phasy sound of Eddy and the Currents?
Actually I didn't know they did but then I think my breakers are just thermal. If these things are very serious issues that speaks poorly of the PSRR is in home audio... Which, sadly, wouldn't be exactly news...
Happy fourth! Remember ears prefer beers to bangs.

You're breakers are thermal? Are the wires coming into the breakers and leaving them thermal, too? ;-)
"Are the wires coming into the breakers and leaving them thermal, too? ;-)"
Sure, I just loosen the screws a little...
Seriously, I've never paid a bit of attention to the loop areas, or their positioning and such, it's just however the electrician(s) happened to do it. If there happens to be enough slack I could do an optimizing pass for the stereo circuit.
Have you actually experienced positive results by doing such things? I don't mean in theory, I mean in terms of readily hearable differences.
Tnx, Rick

Gosh, I always thought you were the theory guy and I was the application guy all these years. Do you mean to sit there and tell me you never wrapped your transformer in mu metal or opened the door of your breaker panel box, or demagnetized your CDs and interconnects, you know, just to see the effect of magnetism on the sound? Color me shocked. Of course, I've experienced positive results by doing such things. Now get up off that lounge chair and do such things!

"opened the door of your breaker panel box"
LOL! Of COURSE I've never opened the panel door' How could I? It's never been closed... I store my ladders propped in front of it and couldn't reach the breakers through them if the door was shut!
Maybe there's a larger, manly principle involved here: sloppy garages make for better sound.
So let me ask you one: Have you tried just taking off the front panel? That should open up the magnetic circuit for several of the current loops. Just askin', not that I would ever suggest doing something so risqué...
If there is enough slack maybe I could reroute the grounds of the stereo circuit nearer the input bus also. Hmmm
"I always thought you were the theory guy". I is! I know more about eddy currents than the McKenzie R. does...
Rick
Did I ever take off the door on the breaker panel? What do you think? You think these hands have been soaking in Ivory Liquid?
Edits: 07/05/14
Not the door, have you ever tried removing the front panel itself which would take the door along with it? Along with all the steel between the breakers.
Just curious, I'm not advocating such a thing of course...
Rick
I have a non magnetic frame and non magnetic door. There are a number of, uh, treatments inside around the romex and breakers as well, you know, unmentionables.

COOL!....
Aluminum? Is the main box still steel? Custom? Stock? Home-brew? Enough questions? Maybe just one more: Of what ilk was the main noticable sonic difference?
Tnx,
R.
Sorry, but that's classified.
Less distortion. :-)
"Sorry, but that's classified."
Bummer, you reverted.
Oh well...

Loose lips sink ships. Old audiophile axiom.
I wrote "PERHAPS you deserve abuse" and I meant it in a sort of jocular way to goad you into producing your own review. Sorry you took offense. Wow, I guess you really paid attention to that previous thread. I was not trying to abuse Winston, and it's true that I don't think he deserved it. I found some others' posts to be unnecessarily cruel and crude, but that's an issue I'd rather not pursue.
Yes, of course a better device might avoid distortion caused by a lesser device it replaces, but no device can REMOVE distortion. No magic crystals, no purified copper wires, no number of kegs (whatever those are), can improve a signal. That seemed to be what Winston was claiming, and the snake oil approach is what set me off. I did not dispute his overall favorable impression of the cords, but only the exaggerated properties he assigned to them. It would be quite foolish, as many others have needlessly pointed out here and elsewhere, to argue against a product one has not personally auditioned.
Looking forward to your review, so long as it doesn't state that these cords make awful recordings sound wonderful. Even mad scientists cannot find a way to do that, especially with just a power cord. I won't argue that it can't make a system sound better, but no one should claim that it can fix something that's already broken.
Peace,
Tom E
not even knowing what the hell you are talking about....not very wise in my opinion, but then that's only my opinion.
The power coming down the AC line is suppose to be either 50 or 60 cycles. It is not suppose to have RF and noise riding along with it. We know, if fact, that there is noise on the AC line. All noise is distortion...distortion is a form of noise....either measured or noticed with our ears. This is the whole purpose of line conditioning....to remove the noise and distortion. The MSA power cords are power line conditioners built into a power cord. What people are describing is a lowering of noise (distortion). If you do not filter it then it gets amplified and radiated by the components down stream....and....into your ears.
So, a power line conditioner or in this case a power cord with a line conditioner built in can lower noise and DISTORTION. This is not snake oil talk.
Granted there can be noise on the AC line. I would agree that, if not removed, the noise can be amplified and will degrade the sound. I disagree that all noise is distortion, except in the very broadest sense of being an unwanted addition to the original signal. The two are measured and quantified separately. Noise is certainly not wanted, but that doesn't make it distortion. I maintain that there is not a device that will reduce distortion present in a musical signal without affecting the signal.
If a filter removes noise from the AC line, it probably will make your system sound better, or at least different. Conversely, I have heard a power filter, quite expensive and bulky, suck the air and life out of a system, and I didn't care a whit whether it removed noise or not. I am not aware that there is any type of filter that will make a bad recording sound good, which is what the original review claimed. If a recording sounds bad simply because of noise on the line, you've got bigger problems than power cords.
I recognize that you're pretty far ahead of me in technical knowledge, and I appreciate your insightful contribution to the discussion. I restate that I believe power cords will change the sound of most components, but they cannot make miraculous improvements to bad recordings. That's the snake oil part.
Peace,
Tom E
