Burn your power cables in PROPERLY with Haglabs Frycorder

I have thousands of hours on my Nordost Heimdall2 power cables. And I put in new Gigawatt inwall wiring over 12 months ago, so hundreds if not thousands on that.

I now know I (and probably most audiophiles here) never had my power cables or power lines burned in, not even close. Because this cheap $300 product by Hagerman Audio Labs, the Frycroder2, has blown me away with only 18 hours on it so far.

A little box you just plug into the end of each power cable. It creates a series of oscillating waveforms, supposedly it burns in the power line all the way back to the first utility transformer.

Who knows if that's true, but already there is a large reduction in hash and grain, more black background e.t.c all the usual subtle things you get with burn in, but seemingly amplified 10x than normal.

I'm going to give each power cable at least 48hrs, so will take a 2 weeks to do and get a full picture after that, but already at this early stage I am a convert and Jim Hagerman is a genius.



Paul Seydor just happens to try the Haglabs products in the latest issue of TAS (May/June 2024). He also is a burn in skeptic and thinks cable changes are mostly exaggerated.

Most of my regular readers know that I am about as far from a wire junkie as it’s possible to get. Over two decades ago, Neil Gader and I did interconnect and speaker-cable surveys, as a consequence of which I vowed I’d never subject myself to such an experience again—nothing to do with Neil, one of my closest friends and always a joy to work with, rather the objects of the surveys themselves

Then there’s my subjective experience, to wit, that most of the claims made for improvements said to be wrought by changes in interconnects, cables, line cords, and conditioners are to my ears usually exaggerated, sometimes little or even no improvement at all, merely a noticeable difference, occasionally worse than before the swap. In order to forestall a barrage of angry emails to our overworked editor, please note that I do not say the differences are unobservable or insignificant, particularly to those for whom they are significant, merely to my mind overstated.

So what was his experience?

I opened the first sample, connected it to the FryCorder2, and let it cook for five days. I then plugged it into the line conditioner (by the same company) and played music for another week or so. One day I cued up Impex’s Sing and Dance with Frank Sinatra remastering and listened for about a minute or so. Next, I substituted the unburned-in cord, which until then I had not even unpacked, and played the same passage at the exact same volume (my preamp has a numerical read-out of the level) for the exact same period of time, about a minute, though I certainly did not need that long. The difference left me slack-jawed—this from someone who has often been deeply skeptical, if not positively cynical about the whole break-in, burn-in business.

With the burned-in cord Sinatra’s voice was warm and rich, with as much dynamic range as the technology of the time allowed, full of life and vitality, with marvelous body and dimensionality. With the unburned-in cord the sound was pinched, thin, and edgy. So, the first thing I did is what I usually do when confronted with something like this—called in my wife Danielle. Now Danielle’s no audiophile, but she listens well and astutely, and her responses are untainted by typical audiophile predilections, prejudices, and pomposities. I started with the burned-in cord at exactly the same level and played the recording for the same length of time, around a minute. Then I told her I was going to play it again, but without letting her see what I was doing, adding that she might not hear any difference at all. Not 20 seconds elapsed before she said, “This is not subtle,” and proceeded to describe the differences she observed in more or less the same or closely analogous terms as I did.

What conclusions can be drawn from my little experiments? Frankly, not many of a general nature that I’d be willing to place much stock in without a far greater variety of source material, more numerous comparisons, much more time spent in the listening, and a wider sample of cords and brands. But the one thing that is clearer to me than ever before is the importance of burn-in, so much so that henceforth I shall never trust my impressions of any wire product auditioned immediately after it’s been removed from factory-sealed packaging. And I shall never again disparage the necessity of burning in wire products.

I like the part where even his wife can hear it.  Isn't that the ultimate test? 

agisthos, The Nordost VIDAR was never meant to be used with power cabling. I use it for tonearm cable, tonearm wiring, and line level cabling.

Hey, maybe this place will turn into Audio Science Review (ASR).

Wouldn't that be fun?

Fun? NO!

I like this mission statement:

The Cable Asylum is for those who have decided that audio cables make a sonic difference. If you do not feel that audio cables do sound different, then do not post here. Posts that state that audio cables sound the same, or that all one needs is zip cord and/or dimestore coax, may be deleted, re-directed or other actions taken at the sole discretion of the moderators or the Bored. If you post more than one such post, you may be banned from the Cable Asylum.



     I have one word, to express my personal view/estimation as regards the Church of Denyin'tology and it's obfuscating, classically (possibly- willfully) obtuse adherents:


                                     Happy listening!

Right, its the Audiokharma cooker that does everything. But does Nordost have a power cable conditioner? Considering PC's are a big part of their lineup you would think so.

Anyway I cannot imagine buying anything else other than the Haglabs FryBaby for line level, considering the performance of the FryCorder.



I like this mission statement: ...

By providing a mission statement that outlines rules of engagement, accountability in the form of active moderation, and a separate location for arguments between naysayers and true believers, A'gon could mostly clean up the pervasive bickering that monopolizes these threads.


That's what this entire hobby is, a bank account burning machine.

 "Burn your power cables” I would add bank acct. to post too! 


                       "...this entire hobby...burning machine." ?

                                         Easy feedback:

                             Anyone that can't take the heat;

                               get out of the Kable Kitchen!


                          ENJOY what you have and know.

                                          Happy listening!

@rodman99999 thanks for sharing your sense of humor! Being decades experienced analog design engineer, including designing devices for high volume markets (100M +), I also carefully select devices/cables/sound-sources/tracks for enjoyment! As of burnin process it’s important for: 1) tube amp after tubes refresh at least 25hr +, with final bias/balance adj. Tube amps also have significant high-voltage and high power resistor degradation, thus need to be tested or replaced often  2) fresh digital devices, if manufacturer skips it (Accuphase for example has 50hr mandatory product run after assembly, to ensure performance guarantee 3) cables - not much degradation there, cables/contacts perform the best fresh
