It's clear, time to move on JJ, let others offer insightful contributions. Perhaps you should consider starting another post about material more familiar to your knowledge base such as a comparison between DTS, Dolby, and Logic7. I would be very interested to read about your findings in this context. Please let us know.

For the record, you clearly do not understand the technical issue at hand, and you have made a clear statement, assuming the mantle of an expert, that is trivially proven wrong. I suggest that you go to the other thread and read the discussions, and then return here and correct your statement.

How does burn-in know what your personal taste is so it can change the sound in that specific direction?

2. Burn-in automatically stops when it sounds right.

When the sound of something is changing, there's no reason it won't continue past what you like. For example: over the course of weeks, the sound of a new component starts to mellow out in the highs while the bass continues to tighten. At some point this continuing change should yield mushy, rolled-off highs and etched, overly-tight bass. But that has never ever been reported to happen.

How does burn-in know what your personal taste is so it can stop changing when the sound is best to you?

Of course, the alternative explanation to the above is that you're simply getting used to the sound. But that's too bizarre and unrealistic to be seriously considered by audiophiles.

Brilliant points!

That's because it's so much easier to read gushing user reviews on forums like this and to read magazine reviews as if something definitive is being said about the speaker. The bummer is that one person says "speaker x is to laid back" and countless newbies are discouraged from trying that speaker b/c of the one specious comment.

Music to my ears. I've been told many times on this forum: trust ONLY your ears! It only matters what YOU like. All ears hear differently. And on and on...

This thread has some of the best (Logical) quotes in a long time and then some of the dumbest opinion ever (how did these people make money to buy AV gear? ).....what a read

and surprisingly Im agreeing with what MarkWriter is posting (its a different side of him from my perspective)

I would assume something like the Dolby Atmos Demo blu-ray on continuous loop would be best to burn in? I know that this is what I use to "burn in" a new calibration on the Trinnov Altitude. How long does everyone let the calibration burn in? Hopefully it is a shorter time period than what is required to burn in the power and speaker cables, and HDMI cables.

Having worked in PMEL labs for over 40 years the only equipment we turned on and let stabilize was an Hewlett Packard Low Frequency Generator or oscilloscopes with CRT's the size of basketballs. The HP generator weighed in at over 400 lbs and emitted low frequency tones for calibrating. As it was in the Air Force PMEL lab which is a temperature, humidity and dust controlled environment the tubes themselves generated a tremendous amount of heat. It would actually affect the air handling system after about an hour after we turned on this bruiser. So I can see how burn in can affect tubes but not so much on small tube amps used for stereo. I would say an hour would be enough for the power supply and tubes to stabilize.

Solid state does not need to warm up. If Fluke, HP and other test equipment manufacturers said you have to warm up a piece of solid state test equipment they would be out of business.

I guess electronic theory would be the next step but that was way back in school and hole theory made my head explode. lol

Klipsch so much it Hz

'burn in' a calibration?

Wait, is this serious, or a Poe?

... I suppose it was inevitable for a 666 numbered post.
