New Pangea Audio AC-14 XL Power Cord

I am using both AC14 and AC14se mk2. While the AC14 sounds pretty balanced, the ac14se mk2 sounds really warm, veiled, and rolled off. The ac14 sounds better to me, airier and more balanced. Is this anyone's experience? I am alternately using these cables on my dac. The 14se mk2 was purchased used, and should be fully burned in. Is more burn in needed?

Have you ever cleaned out the inside of the IEC plug? That may be really dirty inside.  
Does the AC14SE have shiny BLUE THREADS.. woven into the cord cover? YOU should be able to see them flash in bright light. Not a lot of them, but woven throughout the cord cover.The blue threads are only in the Mk2 version. and is the only way to tell mk2 or original AC14SE.

Yes mine are mk2, they have the blue threads.

Also any cord. and includes the Pangea, may take a few days to break in all over again IF it had sat for awhile (months)
So yes I would give it a week before dumping it. Put it on your TV.. or some other appliance if you can. Even the amplifier...
