Does Power Cord Require Burn-In To Sound Good?


I recently bought a new power cord but there isn’t much difference in sound quality between this new cord and the previous Wireworld Elektra 7 which it replaces. The cords are used on the DAC.

Any ideas if the cord needs to burn in to open up and sound better? It currently has about 5 hours on it and I think I prefer the sound quality of the previous cord which costs 10 times cheaper.

Any thoughts appreciated.

Well what I think is that burn in is not enough. I put a heat strip around my power cables to maintain a minimum of 150 degrees F. If you do not do this the burn in reverts to unburn in and then you are back to square one. If you ever let your power cable temp drop below 150F the degradation to your fidelity is quite pronounced. Also you need to keep your power cables suspended above and off any hard heat absorbing surfaces. There is a tendency for the side of your heat stripped cable adjacent to the heat absorbing surface to be a bit cooler. This can cause there to be an unbalanced audio signal which can be quite distracting. Carpet is OK for a contact surface for instance where an oak floor is not. I also recommend that your heated power cable be sheltered from AC ducts in the summer for the same reason. You can never be to careful when the finest outcomes in audio are what you not only strive for but demand.
