I saw this the other day, a manufacturer recommending a 600 hour 'burn-in' period!
What elements in modern electronics can possibly take 600 hours to 'burn-in'?
What does 'burn-in' even mean, does the manufacturer expect the specifications of components to change, and if they do why can't they deliver a product which has already reached its operational specification.
These products nearly always seem to improve after 'burn-in' hardly ever do you hear of a product's sound quality worsening!
I even saw an 'isolation' device for which the manufacturer recommended a short 'burn-in' period!
I would like to collate all the most ridiculous...
