Break in time that extends to months or maybe even years!!


On another thread, we have a well known and well respected piece of gear ( and great sounding too, IME) that according to the member who is reviewing it, needs in excess of 1000 hours to fully break in!! 

While we have all heard of gear that needs immense amounts of 'break in' time to sound its best, usually gear that involves teflon caps, I question whether this very long break in time is the job for the consumer? Is it reasonable for a manufacturer of audio gear to expect the consumer to receive sub-par performance from his purchase for potentially several months ( years?) before the true sound of the gear in question can be enjoyed? Or, is it ( or should it be) perhaps the job of the manufacturer of this gear ( usually not low priced) to actually accomplish the 'break in' before releasing it from the factory? Thoughts...

@atmasphere  Well that's a good point, but according to our esteemed member, on his review of the product, 900 hours has been reached and he is still hearing advances. 
I suppose another question could be...how long is acceptable 'break in' time for a product? Remember that the ARC preamp that utilized Teflon caps was 'supposedly' only broken in after 600 hours! To me, that seems excessive and should have been done at the factory, others obviously didn't feel this was an issue, as the preamp apparently sold well.
@luxmancl38   The size of the teflon cap almost certainly determines the amount of hours it will take to break in. The teflon caps in the ARC preamp were large. 

@cleeds  This isn't a court of law...so your post is a little off, IMHO. The claim that the member made was that he heard that the amp in question was still improving after 900 hours, and i am not going to call him to task for what he heard, not do I have any reason to do so, do you?. That is not the point of my thread, instead, it is as i asked above in my OP.
@ebm  WOW, NICE REPLY...NOT.
If you don't like my thread, please feel free to ignore.
@geoffkait How often are you re-breaking in cables? I have never done that, IME once they are broken in..they seem to stay that way.

@guidocorona   Does what you state in your prior post apply to the piece of gear in question that you started another thread on?
G. Thank you for explaining in detail your reviewing protocol.

I think what you stated makes a lot of sense, and I suspect that there are a lot of professional reviewers who do NOT go to such lengths...

As to your thought about breaking in a mono block in a separate timeline, to that I would say...no. I think the result of what you suggest would be ’flawed’ at best.
G, Now I see what you are getting at with the stereo amps bridged for mono. That would have been an interesting experiment. 
Meanwhile, do post back in your thread when you have had a chance to AB vs the 925's.
@phd  Question is how many users that you were referencing leave their gear on all the time, or listen as often as it takes to actually break the gear in. The ARC preamp I mentioned, would have required a number of months or more...perhaps more than a year, to actually break in IF the user was not listening every week ( and for extended periods). That, plus one wouldn't really want to leave a tube preamp ( or any tube gear for that matter) on for weeks at an end. ARC stated that their large Teflon caps needed 600+ hours to break in! 
@cleeds  ARC didn't state anything about the long break in time in the manual of the piece I am referring to ( I did not say they did, you somehow read that?) , but in a response to a review, this was recommended. I doubt any company mentions much about 'break in' time in their manual..particularly IF it is going to be lengthy.
@heaudio123 Couple of questions for you...

What is your definition of a ’burned in’ unit?

When do you consider an effect 'audible'?



G. You bring up a good point. I do wonder how many times consumers in this hobby do what you do...versus buy something without A) ever listening to it, B) buy it based on price...and usually the higher the better, C) buy it based on a reviewer’s opinion D) buy it based on the recommendation from their dealer or E) buy it based on measurements alone..
