    Jeff,

    Again you are making questionable physical claims without objective evidence to support them.

    Cheers, Marshall.

    what jeff is saying,

    mirrors my experience(s) also.

    Tom, I am familiar with that article and the fact that different types of capacitors have specific characteristics which make them more suited to some applications than others, even between classes of a single type. However the authors were aiming to demonstrate that distortion inherent in capacitors could be audible in well designed audio playback equipment. The distortion levels appear to be below the levels of audibility and there are no details of what, and how, is audibly tested.

    There is no mention of capacitor break-in.


    A similar but more thorough capacitor test article by a well known British audio guy with years of knowledge and experience acquired in the capacitor industry:

    Capacitor Sound


    Again, sub-audible distortion levels.

    Again, no mention of capacitor break-in.

    Where's that burn-in requirement?

    Call me simple minded, but all I need to know is the proof here that at least when I was young my hearing told me all I needed to know WRT capacitor choice in audio ckts.: The "Sound" of Capacitors

    GM, Re The Sound Of Capacitors article.

    It is a bit of a leap to tie the scope pics relating to one parameter to the conclusion made by the author.

    A bit more on capacitor non-linearity: Small Signal Audio Design - Douglas Self - Google Books

    There is much credible information on capacitor linearity(or non-linearity) on the internet if anyone is interested. Invariably you will find that for competent audio designers it does not pose any problem. If one wishes to look at component non-linearity in audio just take a look at vacuum tubes.

    Can these non-linearities be heard? If yes, then they can be measured.


    Still no evidence for capacitor break-in for audio capacitors.

    Re: Altec 604-8Gs and GPA N604-8A crossovers

    There's a non-linearity between listeners that is a key factor in the break-in debate, and it is not measurable.

    Expectation bias.

    It is detectable, though.

    Putting 'audiophile' on a Resume may not be a smart thing to do.

    go as far as re-inventing other peoples circuitry,

    and some p.t. barnum marketing efforts.

    notably tried on diyaudio, against nelson pass.

    see 'death of zen' ....

    i'm not saying he is a bad guy,

    just not all that bright.

    his rant against the 47 systems, 'gain card' ignores the actual innovation,

    in favor of trying to make himself look good, by saying that it s 'overpriced'.

    Where's that burn-in requirement?
    Question for members. "Why do proponents of 'burn-in' invaribly claim an improvement, after it has been done, no matter what is the object of their attention"?

    i read the jung / marsh article, 36 years ago, when it was news.

    the reason i pointed that out was to see whether you noticed what was in that article .

    as you are aware enuff to know that,



    here's a Question for you,

    how come you haven't noticed any actual difference, as new equipment, 'burns in'?

    every laptop i've bought new, had a noticeable 'break in period.

    even the phone i bought 2 weeks ago, is still having the same.

    tomt,

    I believe your Question is covered in #83, here: Master List of Logical Fallacies

    No answer required.

    Great article. I think I work under every single bias they discussed. But, I may be biased.
