Best power cord for Devialet

[K4680]

The length of time to burn in cables seems to depend on load. If you leave them plugged in but with amps in standby they’ll need weeks. I have adapters for power cords that convert the IEC connectors to normal 15 amp sockets so I can plug in a fan or incandescent lamp. So configured, cables like the Synergistic Research Atmosphere HC will take about 150-200 hours to sound their very best. Before that time they will introduce an unevenness in the sonic spectrum, emphasising certain frequencies that can sound like room nodes. You will also notice an increase in transparency and additional detail and air at around the 150-200 hour point. 
In my experience, you should hear about 60% of what a cable is going to deliver within the first few hours of operation. The balance....and I mean that in both senses i.e remainder and equanimity takes much longer. 
Typically cables specified for high current take a lot longer to burn in than regular cables

Hi, I also built an adapter so that I can grind in a large cooling unit (2800W). I let each cable burn in for about 1 - 2 weeks !!
