Does Power Cord Require Burn-In To Sound Good?

So they can make one model for all markets.

I am pretty certain that the person who wrote this has no formal education, physics , engineering or otherwise related but is obviously making a failed attempt to insult those that do.

    Having no formal (or other, it seems) education in Physics; the typical Naysayer Doctrine adherents, will undoubtedly offer their ubiquitous, Newtonian (1800’s Electrical Theory), ceremonial whines, for your Communion and salvation.      

It is not a matter of "So says you". Simple fact, that so many of his claims are wrong or unsubstantiated. He should stop his rants long enough to realize that AD is Analog Devices and still very much in business. BB and LTC were just purchased by larger competitors and the the sub is often better than the pieces.

Does that DAC have a linear power supply? If so there is 25-100 ohms of wire in the transformer. Do the math

ryder OP1,074 posts12-04-2020 10:09pmThanks for the responses. I'm seriously hoping for good things to come from this new cord as it's a pretty heavy investment for me. I hope this burn-in thing with cables is something that works ie. noticeably if not drastically improved sound after the whole burning in is complete.

Hey, I am developing a fondness for oldhvymec's unusual ramblings. Sure, I don't have the same "belief" that he has in the differences between cables, but buried inside many of those posts is a much healthier skepticism than a lot of audiophiles.

There is a difference between the same "specs" and measuring the same under a range of test conditions. If they measure the same under a variety of test conditions then it will be hard to tell them apart  (just like what happens in blind testing, where people have a hard time telling differences if they are able to at all).  Tubes rarely measure the same so there goes that out the window. Wire inside the amp ... you will never be able to detect that change unless we are talking shielded/no shielded for a low level signal cable or an undersized higher current carrying conductor. Good grounding actually shows up in detailed measurements.

If someone did actually threaten you in a private EMAIL, you should bring that to the attention of the moderators. Call it "tattling", but odds are you are not the first.

I dont know why do audiophiles claim to be in search of high fidelity when it is obvious they aren't?

Not sure who you think you are fooling with this? It’s obvious you don’t have a physics or eng background. If you did you would calculate and clearly communicate , with some hard numbers what your claimed dielectric impacts would be on a power cord supplied by a source (AC line) with a source impedance at audio frequencies of about 0.5 ohm.

You won’t do that though as that would take the exact knowledge you claim others don’t have.

rodman999994,822 posts12-12-2020 12:14am@audio2design- I’m absolutely certain (experientially); you’re absolutely wrong. Yours is simply another uninformed, Naysayer Doctrine adherent’s assumption. Now: deny the possibilities, offered by the facts presented.

Perhaps but that would require ignoring the ops question. Do they not deserve an answer?

It's one less thing to worry about for multi market and makes for easier MFG. Only need really design for 2 or 3 voltages but way more cord ends.

- No, don't buy it. Different voltages in different countries can't be remedied by power cords only.

You know what happens when we were recording and we detected a faulty power cord? We replaced it then shut the studio down for 2 weeks.

Sorry bit of professional humor. We replaced it. No one noticed. Usually it was replaced due to damage/safety not actually failing and we replaced with new. Generally heavy duty as they took a lot of abuse. Then again could be just that the artist forgot the power cord to their amp, synth, etc. Never once do I remember them insisting they had to run/fly home and get their own cord (or let it sit for several days).


Now obviously recording and playback are not the same but the people who make your music don’t fret over this, don’t even give it a thought actually (except hum and noise). For live recordings the equipment including orders of magnitude more sensitive microphone cables were probably set up that day or if lucky the day before and no one gave any thought to the power cords on mic preamps, mixer boards, amps, etc.

Oh, contacts ... That's where problems existed most of the time. Contact cleaner/enhancer is your friend and sometimes tools to fix a bent pin.

Respected recording engineer who has published a lot of nonsense like that silly test at RF of cables with Kimber and tries to claim it applies to audio (showing technical ignorance), or his claims to have eliminated masking from loud sound ( I call bull), or to raise tinnitus inducement by 30db (bull). I love his rants on crosstalk in op amps which I don't dispute but claims the audio is triangle waves internally is not accurate, and at best implementation and op amp dependent. Convenient to invite the variable and huge crosstalk in the predominant at the time vinyl playback. My favorite though is probably claiming electronics can ameliorate room issues.

And proof of his claims ...
