New Pangea Audio AC-14 XL Power Cord

After a day breaking 2 in on the amp and power conditioner, I moved the Pangea AC14XL to the preamps. The sound improved a bit, adding a bit of happy to the treble sound.         
Got a few more arriving today. They too will get put on the amp and power conditioner for a day.. Then one on Marantz SA-10, and I have to play with the other two.

I have 3 14XL ,one 15 feet  long , notable jump up from other 14's .

A few weeks later.. I bought 12 Pangea AC14XL power cords.Definite improvement over the AC14SE mk2 Signature.I am using the XL on the amp and the power conditioner as they are way better sounding than the AC9SE mk2 Signature. A lot more clarity.
One thing I highly recommend is cleaning out the IEC holes in the cord IEC plug. There is s ton of crud in the IEC plug.
First I pluck off 2/3 of the cotton.then flatten a dozen Q-Tip with a pliers. need the type with a paper stick. Then I use Meguiars Scratch X automotive finish stuff and put some on the Q-Tip. stick down the holes. rub around. black crud comes out. (I will pluck off some of the dirty cotton and use it more) repeat. maybe repeat third time! Then I use Caig ’RED’ cleaner preservative... brush in, use another Q-Tip to rub around. More black gunk. repeat. Then final use Caig Gold new Q-Tip rub a little . done. also polish the blade tips (which also leave a lot of black gunk at first) with the Scratch X and Caig Gold them too.                    
By the way they are still on sale as of 01/01/2019

Of all the Pangea Xl power cords, I do not like the XL on the amplifier. at it was too something compared to the  old cord. (direct from the wall) Put back the home made with DH Labs $8 ft wire, and Furutech ’28’ type Rhodium plugs. Just a little warmer (also fuzzier...) sounding final product. The rest of the Pangea AC14XL seem fine. Great clarity.

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?
