Break In Question?

Ok, enough time spent on this. IMO, there has not been a single on topic direct response to my claims, which have been reinforced with testing and examples of new drivers in speakers. An objection stating, "I heard this over x period of time," is not a serious challenge to my practically instant comparisons. Nor are they a serious challenge to my examples of switching out old drivers for new in speakers. 

BTW, i have never paid any attention to Audio Science Review. I believe over the past years I saw two titles of videos that I thought might be interesting, but neither one was relevant to real world system building. I concluded I can safely ignore that source.Objectivists can make as many mistakes in system building as subjectivists who claim break in is real, i.e., that the equipment audibly changes its performance over initial use, 

There, that will win me a lot more friends! In the book I also discuss the pitfalls of objectivist audio and how it hampers system building. 

jrdavisphd, I was just about to walk away from the thread for an indefinite time period - some may have cheered! - when I saw your post. 

Thank you, sir! I hope that the work is a boon to your involvement in our hobby! 

@douglas_schroeder What exactly is your position in terms of publishing your book? Someone as a scientist or someone with an opinion? How long have you been in this hobby?

There are many great speaker manufacturers that recommend burn-in on their speakers. Arendal for one used to recommend 60hrs or something. What exactly do you have to offer over an established company with a ton of experience and R&D?

"Break-in" is the age-old answer for getting home after spending $20,000 for new equipment and it doesn't sound any better than the old setup.  Answer:  You need to let it break in.

You spent $5000 on new cables, hook them up, but they don't sound any different - answer: you need to let them break in.

After 100 hours of "break in" you forget how the old system sounds, you have a cocktail or two, and all of a sudden your new system sounds great!

I love this hobby.

Paul McGowan, of PS Audio fame, probably knows as much as just about anyone alive about high quality audio electronics, says break in of amps, pre amps, dacs, cd transports etc is most definitely real & necessary. Of course, breaking of loudspeakers is a given. I had a pair of Dynaudio Contours that took about 200 hours before they settled down & didn’t sound a bit hard on the upper midrange, lower treble.
