"Burn in" Are you serious?

Disclosure: being new to this hobby, I don't have a lot of experience either way with this. My dealer told me to burn my stereo in and not to listen too critically at first, and I followed his advise. As a result, I have no idea whether or not my system 'burned in'. Furthermore, I hope no one construes my last post to mean that I disavow science. I am much more likely to believe an explanation grounded in science than one based in faith (especially if that faith is based on frail human perception).

Robba; respectfully; listening to/enjoying music is somewhere beyond science, at least at our present state of knowledge. Music, IMO, is an art form. When you look at two paintings and like one but not the other can that be explained scientifically? But as your appreciation grows, maybe you'd like the 2nd painting? This has happened to me many times with music-- sometimes it grows on me-- as I grow personally. Except to say it's psychologic, I can't expalin this phenomena "scientifically", and it can't be "tested". Craig.

.......yes, I realize that my above post argues for both sides of this issue. That's part of my point. Craig

Do I change or does the system? Maybe its a little of both.

Bmpnyc:What I trust is my hearing and my mind. Feelings can undermine the evaluative process considerably. I've done the cable comparison many times with variously priced wire. New on trial and well-aged loans from curious and cooperative friends. I also have a significant part of a twelve guage roll which has never to my knowledge had a single electron flow through it. Equal unused lengths compared to identical original cut lengths (aged about 3to4 hrs. daily for 7 or 8 years) sound identical to my well seasoned ears and measure the same also. I do admit that I've not personally done this experiment with hyper expensive wire(over about $300 a meter(that's hyper expensive to me)). Perhaps physics and the "burn in" effect are cost sensitive. As I've said, I'm open to convincing proof otherwise. If the test is not truly blind to the listener, then it cannot be considered objective. Let me finish with two simple questions. Would you say that you honestly would not have ANY expectations when doing (e.g.) a sighted comparison between a Krell and a 1978 Pioneer receiver?...or between multistranded solid silver cable and a straightened-out coat hanger? ( if doable,try the coat hanger.You might be surprised) Best to all for the Holidays.
