Quote Evie McCreevie:
I've recently got a new pair of AKG 701s...
Various 'authorities' on the net recommend 'burning-in' for 300(!) hours. Others say it makes little or no difference.
Surely this can be proved conclusively - once and for all - by some boffin or manufacturer?
Simply measure any decent cans' response when brand new, then after burning in. Check for a measurable difference, and evaluate if that difference is in any way beneficial.
Has this been done?
I have various things from various manufacturers.
But with the K701 it seems that the consensus is that it needs a very long burning in time and I think about 500 hours is the norm for these.
I know 0VU had (has) a pair and I am sure he said that they needed a very long burn-in; were pretty nasty at the start and great when finished.
