It seems like such a bummer to buy in to the audiophile burn-in myths, where every damn thing you buy doesn't sound right until hundreds of hours of use. Some audiophiles were discussing new capacitors put in their amps, which "took 1,000 hours to truly burn in and reveal what they were capable of." Cripes almighty, what other consumer items would ever be sold on the grounds they just won't work right for hundreds of hours?
I just had to re-tube my amplifiers. Per audiophile myth, they will take at least 100 hours to burn in the tubes. Per my ears: things sound fine.
