Power Cord for Power Conditioner

Hmm, noticed that Lacee's favorite power cable manufacturer was using a Yokogawa oscilloscope for some development work.

I've got the same scope in our shop at work (and its big brother) and they come with a low cost detachable power cord. Depending on measurement location ours are often also tied to a really long extension cords, sometimes even a string of two or three.

I guess that since power cords change the output of quality electronics, all of the scope measurements are meaningless unless referenced to a specific power cord?? Weird that manufactures of measurement equipment for industry and medical services & etc don't know this stuff.

Jeff, our hobby is about sound.

Sure measurements matter,and so it goes.
Some folks are about sound, some are about measurements and seldom do the twain meet.

Sort of like politics.

Now , I think that your workplace would be the ideal location to insert a few upgraded power cords.

Then you can "listen" to hear the difference they make.

Oh, sorry about that,in your case it's not about the sound is it,so you are stuck with trying to let the measurements "speak" to you.

Like I said , two different worlds.

"Some folks are about sound, some are about measurements and seldom do the twain meet."

Agreed, but power cords don't know the difference between signal amplification for sound and signal amplification for measurement or any other purpose. Either they change the output of well designed equipment (putting research, medical diagnosis, and etc. at risk) or else they don't.
Would be interesting to visit someplace at the heart of state of the art electronics, say fermilab, and see if you can find one single 120v power cord that was beyond what you can buy at wall-mart.

Jeff have you ever heard the sound that measurements make ?

Do measuring instruments have a sound,like amplifiers do?

Look at how many different sounding amplifiers there are today, that on paper all measure the same.

Some things have yet to be measured and sound is one of them.

No one has heard the perfect replica of the original event and there is no absolute benchmark of what it is.

Unlike the lab gear you hold in such high regard, hifi gear isn't just a function of meeting the specs.

You'll hear what bad specs sound like and what good specs sound like, and sometimes a poorly speced amp(like some SET amps) sounds more realistic inspite of this. anomoly.

But this is just falling on deaf ears(literally) if you feel that all amps sound the same.

And the same can be said for power cords.

I know of one manufacturer of a line conditioner who now sources his wire direct from Germany because it not only measured better than what he had been using, but also sounds better.

This wire is the type of wire that is used in several research labs in Germany.
The manufacturer of the line conditioners was a cable skeptic,until he came across this wire.He revamped his product and now uses this industrial wire exclusively.

Audio is just a hobby sideline from his real profession as an industrial engineer setting up lab measuring devices throughout the world.Devices whose reliabilty depend on the quality of the electricity being fed into it.

The man is Ed Wolkow, his sideline is Foundation Research.

"Look at how many different sounding amplifiers there are today, that on paper all measure the same."

That is actually just something someone made up, I guarantee it did not come from an electronics/measurement type person.
The goal of a good manufacturer is to control quality to the point where there aren't measurable differences between components that are supposed to be identical (e.g. mono blocks), but there are measurable differences even when everything that can be done to prevent them is done. The other thing is that your components are constantly changing, a twelve month old amp will not measure exactly the same as it did the day you bought it. All devices (resistors, inductors, capacitors, transformers, etc.) are constantly either breaking in or breaking down and no two devices are ever exactly the same. The bright side is that as long as things don't get too far out of tolerance specifications, nobody can hear the difference.
I quit stereophile quite a while back, but they used to make amp measurements if you wish to confirm that no too amps of different design measure the same.

"Some things have yet to be measured and sound is one of them."

If it can't be recorded/measured then there is no way for it to be played back on your stereo.

"You'll hear what bad specs sound like and what good specs sound like,"

Interpreting good versus bad is where things get really interesting and also get to be very much about personal preference.

"But this is just falling on deaf ears(literally) if you feel that all amps sound the same."

Even if I believed that I'd still be forced to admit that they measure differently and I couldn't debate you. It is the opposite of the power cord thing.

I'm not going to comment on your reference to the specific company and individual. I think it is aok for you to bring it up in a positive sense though (and as far as I know this may be a great company).
