Burn-in revisited

A while back I found that cable direction really can matter, so now I'm a firm believer in that at least. As to cables I understand they change properties insulationwise and so forth so it may not be as far fetched as I before held it to be.
Since I started caring more about quality sound reproduction or true HIFI about a year ago I have found that the most mysterious aspect is hands down the power or electricity bit.  For instance changing the position of a power cord in the wall socket by 180 degrees (I live in Sweden which has two pin mains outlets so this is possible) can have tremendous impact on the sound quality going from slightly boxy and a bit boomy to clear as day.
So the idea of, basically, power or at least current handling interconnects maturing seems absolutely plausable.

The last two posts inspired me to quickly unplug and replug the mains lead of my PSU1. It does seem less boomy but I may just be listening for the change Johan described above.

Yes, they usually work and at $49 US it's better than DIY for most users.

I've made a few but I don't think I could match that price.

An audio signal is only really necessary to burn in components that are not powered (that do not draw direct current - DC - when switched on) - those only in the signal path or those with zero volts at either end as in dual rail supply equipment. The vast majority of components inside our unipolar supply products intentionally draw DC so the burn in device may not achieve much, but worth a try.

I have been experiencing some distortion with tracks and after pausing the track for even a few short seconds the distortion disappears. My headphones are a few months old but have never been properly amped and my 3.5mm to phone cable and novo amp are brand fire new I was just wondering if it's the amp needing to burn in or whether it's low quality sound files or worse case knackered headphones. Obviously I'm not asking for a diagnosis but some simple advice on bedding in for amps headphones and cables.
