AC Power Cords (again)

[Rutgar]

I know this has been beaten to death, but here is a recent review that I thought merited mentioning:

http://www.hometheaterhifi.com/volume_11_4/feature-article-blind-test-power-cords-12-2004.html

Looks like their results show that power cords really don't make a difference. Save other than a placebo effect.

...even if that... ;)

oh it seems to mean reviews are more reliable than your own ears lol

bad news is placebo effects do get to me with my portable radio now sounding like a pair of wilson speakers ;-(

I posted only that link in the Fourth Post of the AC Cord thread... I figured I would leave it at that... :) The endless round about after gets you really no where as far as I'm concerned. Though it is fun to watch :D

[Rutgar]

I was wondering if this link had been posted already. But, I thought the review was interesting enough to warrent posting again. And you're correct about the endless rounds that usually come up, with this topic of discussion. But, I think this review lends a little bit of scientific support to the nay sayers of AC cords.

just tried the wattgate audio grade iec 350i:

www.wattgate.com

more solid bass and more musicality and the highs have more air

only using cheapo copper wire !!!

[cpu8088]

just recently read a magazine with photos of nordost products

indeed the nordost power cords are using the wattage iec 350 audio grade connectors

Why do you think manufacturers of various scientific instruments such as electron microscopes, chromatographs, devices that measure electrical activity at the cellular level, etc. don't use such products?

Chu:

Now that's gotta be because those scientists don't know that they could be watching those cells on more inky black backgrounds or that they could reduce all that induced cellular background noise. LOL

I hope there isn't anybody at the hospital doing double blind tests with the lab equipment. The OB doc uses Nordost power cables, maybe he hijacked one from the ultrasound machine up in Labor and Delivery.

Seriously, I have a biomedical engineering background and have worked with lots of medical diagnostic equipment. Most medical instrumentation uses Belden cable and rugged grounded connectors for power cables (about $20 from Volex). On the other hand I never played a Pink Floyd CD through stereo MRI machines to determine if I could hear the difference.

Sorry guys it's been a long weekend and I couldn't help it.

with electronics Mark Levinson has been using military grade components for a long time, and some european electronics have been using so called hospital grade components for a long time (FM Acoustics, Goldmund, Gryphon)

i am sure your hearing ability and that of ob will be different (not better or worse). or you are hinting that all our hearing abilities are the same?

[Dizzman]

before doing anything on buy snake oil... please read this white paper. And then think abou thte right way to fix things.

WARNING, the writer is very technical and this was designed for an engineering crowd. But you may well enjoy

Well that's nice, but so what? You use the part that you need and sometimes you gild the lily to add perceived value. It's not unknown for companies to use parts that do nothing more than less expensive parts.
i am sure your hearing ability and that of ob will be different (not better or worse).
Of course.
or you are hinting that all our hearing abilities are the same?
Nope. I'm willing to give anyone the benefit of the doubt and assume they have hearing that is that of a youngster and can differentiate a level difference of about 0.1 dB from 1-4 kHz, give or take a bit. In order for some of the claims that you or others have made with regards to power cords, then there must be a difference in the signals at the speaker terminals sufficient to exceed what's known as Just Noticeable Differences. Now, are you hinting that ob, who I assume is an older gentlemen, has hearing that is orders of magnitude more sensitive than that? Or that his hearing is as reliable as a cheap microphone hooked up to a <$20 sound card when it comes to accurately determining the location of some sounds?

[Dizzman]

try these devices first...

http://www.exactpower.com/ep15a.html
http://www.surgex.com/

these are REAL devices with solid and properly done engineering behind them. Before spending any money on other than a simple (heavy duty) IEC cord, i would put in something like this. Without doing these types of things in the first place you are quite simply wasting money. i understand that many feel that the exotic cords do provide an advantage (a listserv discussion on Shunyata Research powercords that i was in was quite hysterical as their literature and product was torn apart by many people with tremendously strong engineering backgrounds) But the advantage that these cords MAY provide is questionable at best, these power conditioners provide benefits that are measureable in many cases. YES, I SAID MEASUREABLE!

[Michael Grant]

Dizzman, thanks for the PDF link. Looks like a great article that is going to take me awhile to digest, and I'm sure I'll enjoy doing it.

[oneobgyn]

Now, are you hinting that ob, who I assume is an older gentlemen,

I am not sure if this is a compliment or an insult :(

[Dizzman]

which part? The older, or the Gentleman part?

[Chu Gai]

Although the benefits are measureable (I didn't see any meausrements at EP nor was I able to find a legitimate publication such as TomsHarware or AnandTech do an objective review illustrating such purported benefits), one would have to establish that the equipment had a problem with the incoming power to begin with or is the reason for buying such products simply because one is concerned?
OB, I didn't bring your name into this. I just figured you weren't a teen-aged girl which probably represents the category of people with the most acute hearing.

No doubt about it--I wish that I had the hearing acuity of my teen-age daughter

[Curt Palme]

MikeTz- LOL! Well said!

Thank you... i try, god knows i try
