  Power Cord Burn-In
I know, I know...this has been posted before but I swear I searched the archives and couldn't find what I was looking for so here's my question:
Just purchased a new pc for my cdp.
Can I burn this cord in without turning up the volume( family factor) and can I leave my preamp and amp off during this process. In other words, can I simply throw a disc in my cdp and press play/repeat and let the music play with no volume?
Thanks!

I also do what Panny does, but only for 4-5 days.

Computers are good for audio AC cord break-in, they have 100-200 watt power supply and don't tie up stereo system.
Turn off sleep/hybernation power mode on computer when using to break in AC cord.

I have to agree with you, Drrdiamond. I just got finished burning in a TG Audio SLVR power cord over the course of 5 weeks, on a combination of a SS amp that's on all the time and a chest freezer. The process was very instructive.

I tested it three times during that period, comparing it each time on the preamp in my main system to an Elrod EPS2 Signature that had been powering the preamp for several months. The first time, after two weeks, the TG was much worse than the Elrod - it made the system sound lean, edgy and bright. The second time, after four weeks, the TG was almost as good as the Elrod, but not quite - the edge was gone but it still sounded lean. The third time the sound with the TG was better than with the Elrod - it was smooth, transparent and fully fleshed out, and in comparison the Elrod now sounded slightly thick and plummy in the upper bass, with an attendant loss of detail.

I doubt that mental acclimatization played much of a role here, because each test lasted no longer than an hour, and the trials were separated by at least a week. The change in the SLVR's character over time was quite striking. I just repeated the test for a fourth time after having the SLVR in the system for a week or so, and the results were the same, to my ears, as the third test.

I'm quite prepared to believe that some power cords in some systems don't exhibit these kinds of changes, because I've used other PCs where I never noticed any changes at all. Bob Crump, the man behind TG Audio, is adamant that his power cords take this long to burn in and settle down, however. Based on what I heard, he is absolutely right.

08-09-04: Essentialaudio
Morbius, I'm well aware of what FCC and BCC structures are as are others here, but you might want to look up Dr. Rolf Hummel's book wherein he exhaustively explains in technical terms how and why the break-in phenomenon occurs, covering high and low temperature annealing among other topics. From those who have the book, it is a definitive reference. Few have the equipment and know-how to measure it, but it can be done. I believe Dr. Hummel is at Univ. of Florida.

Dr., are your comments based on your listening experience or just theory? I am also a Physicist but I have learned not to take myself too seriously as you obviously do. Did you just receive your Ph.D.? I have learned over the last 35 years in audio to rely more on my "EARS" than Maxwell’s equations, etc. Stop being so pompous.

08-17-04: Boa2
The answer, Scottht, is YES. I did blind tests on my Jolida JD-100A with three different PC's, and all three people listening agreed that while one of the cords was more open than another, a third (a Michael Wolff carbon PC) made everything sound live and three-dimensional. In fact, my wife guessed that the most lifeless of the three must be the Wolff, because we had just received it, and she figured that "it must need breaking in." She was quite surprised to find out that it was in fact only two hours old. Now three weeks later, it sounds better yet.

I will say that after hundreds of hours recording and producing music, I have a pretty trained ear for slight variations in sound. And yet, the differences with the Wolff cord were not marginal. It was dramatically better than the others. I have affiliation with Michael Wolff, other than as a grateful audiophile whose expectations for his audio system were expanded by his products.

Dear Morb,
It's also a non-sequitur to discuss the JFK Jr problem, call it "fallible senses vs instrumenation", and then use that as a proof of the limits of hearing. In fact, your comparisons are apples-oranges.

You were comparing an optical sensor (eye) with, what, EM radiation sensors(?) under conditions where the optical sensor is severely disadvantaged. Had you compared optical to optical (e.g. eye to camera, telescope) you would have discovered that the instrumentation was no better than the eye under those fogged in conditions.

My point was to say that human sensory detection uses a wide variety of criteria in arriving at conclusions, and is subject to a high degree of training (yes, pattern recognition). Agreed, it has nothing to do with electron flow, and neither does your commentary. But my point actually does have a great deal to do with why audiophiles, as well as audio professionals, become skilled in hearing fine differences, and also with a discussion on the fallibilities of double blind tests. Lets not get into blind testing here; it's a long and heated argument.

It's a necessary and good exercise to look at audio "theories" in terms of well-established scientific knowledge, like phase diagrams and electron flow. But it's also a little dangerous to always infer from the text book situation to the engineering situation; the devil is in the details, and human ears need to be trusted at times to tell you that you haven't always got the explanation right.

Gosh, let me think about that just 1 minute. No kids, no mortgage and no debt. I don't know what I would do!
Most certainly the best stereo I could find. Enjoy it while you can. My oldest daughter is going into 10th grade. And my youngest is going into 8th grade. I have 15 years left on my mortgage.
I guess that is why I am using signal cable power cables :)

Hi Willywonka620

For me as long as current is going through the power cord it is getting broken in.

Using a Kill-A-Watt I've measured how much my equipment draws and then I use an IEC to plug converter (C14-5-15R) to then use my power cord as an extension cord.

Here is one example from Mouser:

http://www.mouser.com/ds/2/411/P002002-28453.pdf

I've used power cords as extension cords for lamps, vacuum cleaners, irons, steamers etc. Pretty much any piece of electronics that would draw more than my equipment.

After all that it gets installed on my audio gear and I sit back and relax. YMMV though
