It seems we all have different experiences concerning break in. I have 7 pair of bookshelf speakers and most seemed to change sound over time. I have a Loki Max EQ and I would need to control brightness for a time. After the so call burn in, I would no longer need the EQ, I have 4 integrated amps. Hegal Mac hybrid, Accuphase and Pass. Out of the 4 the Pass definitely went through some type of break in. When I first plugged it up, the bass was very strong and it sounded very dark. After about 200 hrs or so, it became very sweet and natural sounding.
Burn in vs perception
Posting here in speakers, but could probably go in any of the forums. Question of the night: how much of burn in of components is actually burn in of our perception? That is, is burn in partly us becoming accustomed to a change in sound.
I’m listening to my SF Amati Traditions that at first I found a bit strident, but I now find lush, dynamic, and generally brilliant. I bought them as 1-year old demos so theoretically they should have been played enough to be broken in. I haven’t changed anything in my system—I have been working on my room with more stuff, but that’s it.
Sometimes reviewers or arm chair audiophiles (me) will state that said component needs to be plugged in and left alone for weeks until it gels with the system. Could this simply be our own perception burn in OR is something real happening here?
For speakers I can buy it (woofers need to loosen up and all), but I almost always buy used, and I almost alway a) find a difference of a new component (good or bad), and b) in time, I couldn’t tell you what the change was. Maybe just me, but our brains are pretty good level setters.
I willing to bet this can be a large part of “burn in”.
