Beware of the cable claiming long burn in period.


Almost all the audio equipment including speaker need burn in time.

But I had bad experience with one digital cable recently.

Some people blew the horn on it and claimed burn in time more than 100 hours.

Out of box it had lot of details but etched.

After 8 weeks (around 200 hours) it got little bit better but its overall performance is not better than other digital cable that I have had.

Now it is too late to return it.

Beware of any cable claiming more than 50 hours of burn in time.

The chance is high that you will waste your time and money.

I think in 300 hours of burn-in what happens is your head burns in--if you want to get scientific about it one would need a double blind test--check out audioholics on youtube. A signal is a signal!
Why should you beware of cables with long burn as this has no correlation with the sound of the cables.It also has nothing to do with the quality of the cables.
If manufacturers stand behind their claims that their cables sound better after significant burn-in, then they should, as standard practice, offer those products fully burnt-in, not as some optional, add-on, and always more costly extra.  Who else brings a product to market that's only 90% there?  (On second thoughts, don't answer that...)
If the burn in happens in your head and you need a double blind test to prove it we call that burn out, not burn in.

Many new cars come with break-in instructions. Some are delivered with special oil that must be changed at the end of the period.
