Burn your power cables in PROPERLY with Haglabs Frycorder

@retiredfarmer that’s not inaccurate but I think you might be misapplying the sentiment in this case. In the absence of tractable metrics for a process/device like this, anyone with a reasonable understanding of experimental design (and/or psychology) will acknowledge the only option is a properly controlled preference study.

No reputable university will train people to base their understandings on anecdotes, no matter how abundant an online community may profess the anecdotes to be. Understanding comes from factual evidence. Belief comes from personal experience and/or unquantifiable anecdotes. Anecdotes are not evidence, but evidence of audible difference can be sought with properly controlled preference studies, even in the absence of digital test protocol/equipment.
So it’s left up to the purveyors of such devices as “cable burn-in’ers” to test (for consumer preference). The question “Why don’t they just do it?” is begged, the true answers probably being:

(1) it’s not free of time, money and other resources,

(2) it’s possible that less-than-favorable results may be had, and

(3) why invest (1) and risk (2) if sales occur without due diligence (1 and 2)?

Yeah - who likes it when a question is used to answer another question, right? 😉

One question about consistency of design philosophy, given the alleged importance of such things as cable burn-in being sufficient to warrant Hagerman Labs developing multiple devices for the purpose, … how does burn-in affect the cheap switching power supply for the rave-reviews-phono stage Hagerman designed - the current 3rd gen model that replaced the previous inbuilt PSU-versions of the Trumpet? Advocating a flagship phono stage that’s powered by a Chinese wall wart to the same folks you’re selling “cable burn-in’ers” seems to me a double standard. What am I missing?

Disclaimer: there’s little skepticism in my mind that the Hagerman phono stage is probably great (I’m particularly partial to certain 12AX7’s, so bias be had!), and I’m not one to assume a properly matched switching PSU will audibly degrade all stereo playback components. What’s curious to me is that I usually see a pattern of folks who say (A) LPS is a must for everything x cables / burn-in is real. Folks who hold (B) cheap switching wall warts for an analogue stage being fine x cables need unmeasurable burn-in, to be simultaneous truths would, in theory, be a rare breed indeed, no?

Overthinking this, surely, but, I like to know the process behind patterns I sense. Lest the patterns not be real patterns at all. 😆

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

Wouldn't that be fun?

My stereo makes me so happy now, any change would surely be anticlimactic. I will use the energy to find new interesting music.

Hello Agisthos,

Here is a person talking to you who really tried it out. I tell you how I bought it. A friend of mine camed to my place with a hijiri nagomi powercord. It was better than all my powercords so I decided to buy four of them from the same shop for my setup. When I got them I was really sad because they doesnt come close to the soundquality of my friends nagomi... :( I called the shop and told the shopowner that the cables maybe are fake! He promised me that they are for sure NO fake because he bought it from the distributor for germany. Then for my luck he remembered that he burnt my friends cable in for two days with a hagerman labs frycorder 2. Then he sended me his frycorder to burn then in by myself. And in the end it was the same soundquality. No it was even better because I burned one cable in for two weeks. This was the bestsounding cable. Then I wanted to buy the frycorder from the shop but he told me he won't sell it because its his own exemplar. Then I ordered one from haglabs webpage. Since then all my powercords have minimum of two weeks burn in and the frycorder works all the day. When I don't listen to a unit of my setup the powercord sticks in the frycorder. ;) Now I am interested in the snakeoil and electricitystudent comments from people which never try - just pray their useless non-fact-based opinion. :) Sorry for my bad english but I am from Bavaria/Germany. 

Kind regards from lake Tegernsee, Andreas

@andili That's interesting to hear because I was wondering what is really going on - is it the burning in of the main line that gives all the benefits? or does putting hours on each individual power cable have an effect?

According to your experience the later. I am doing 48 hours on each line so by this weekend will have the whole system done and can do a proper listen.

True there is a lot of snakeoil and useless products in this industry, but this one does something that is immediately obvious. And its so cheap at $189, that's a drop in the bucket - I have other tweaks that do far less for far more.
