In Reply to: RE: Why it might be better to listen carefully during the "break-in" period posted by genungo on June 09, 2015 at 05:56:29
"What if the sonic changes we perceive during the "break-in" period are at least partly due to changes in our hearing during that time? "Two things:
There is no such thing as becoming accustomed to the sound. Every audiophile knows that.
And, all manufacurers have already "broken in" their speakers, which is why they know exactly how to exactly design their precision crossover networks.
A third thing...
"Break-in" is bullshit.
Genungo, if you're not careful, you'll become too knowledgeable to be an audio industry "useful idiot".

You will find that your ears will adapt to damn near anything. In other words, your brain doesn't know flat freq response from a hole in the wall.
What most people perceive as break-in to me is just the smoothing out of the rubber cone surrounds as they work the kinks out and the first few hour of hell that all capacitors give when they are brand new.
I can immediately spot any serious deviations from neutral response or non-linear distortions. Not pinpoint them -- that takes measurement as always -- but can definitely hear when "something is wrong" in approximately which frequency band. Some distortions my ears/brain just won't adapt to.
Have some speakers I built a couple of years ago, using some 5.5" Peerless midbass drivers and BG Neo-3 PDR planar tweets. Original XO was at 1950 Hz, about as low as you dare go with those tweets. Modeled well, measured close to modeled response, but just never sounded right. Could never enjoy those speakers. Recently rebuilt to XO with steeper slopes at 4kHz, well within the extended flat range of the Peerless drivers AND much further into the comfort zone of the Neo-3s. Huge difference -- they now sound quite nice, and really show off the shimmer and sparkle of those planars that were previously muddled by low-level distortion.
I know some DIYers tend to initially like whatever they build. Not me. I listen real hard right at first for what sucks.

That is one of my greatest fears - hearing shit from a labor of love after building new speakers.

I usually find that the first 20 minutes will let you know what the final outcome will be.The final product will be more refined and finer hued,but you will get a glimpse.
On the other hand,I hate break-in devices and de-mags.They leave the product being broken-in sounding sterile and usually induce a resonance in the 4-5Khz range.I usually slap on a CD with good bass reproduction (I am walking CD) and let things go.I also feel that turning the equipment on and off,as in usually listening is just as essential. YMMV

Hopefully, you're kidding, and that you know that I was being facetious.
