Nordost blue heaven burn in

[stephennic]

Hi,

Just had a lend of the Nordost Blue heaven interconnect, how long does it take for them to burn in. They are very detailed, punchy and open however a little hard in the mids - does this settle after burn in, what changes would you expect in the sound?

These are charicteristics of equipment not cables!
