Best power cord for Devialet

[sam1000]

What are your experiences in burn-in time of High Current power cables (I am using two Audioquest Thunder for Devialet mono amps - two 220 Pros). How long does it take and to what extend will it improve performance?

If you don't hear any improvements after first 24 hours, time to send them back :-) What power cord did you replace these with. For e.g. if you replace Mansoon with these, you will be hard pressed to discern the difference.
