Power Cable Suggestions.

I am looking for a new power cable. I am looking into spending anywhere from $300-$500. I am torn between a Furutech Astoria Plus, DH Labs Power plus/cryo and last but hopefully not least, CullenCable Cross Series II. I just learned about CullenCables today and they look very nice. This cable will be used to power up a Naim SN3 or REL T7i. There is Morrow Audio which currently has a 25% off on all their power cables. I need a power cable asap. Any help will be very appreaciated.
