Cullen makes great cables at their price point, and were a definite upgrade from my old Pangea cords......huge value and well made.
AntiCables Level 3 PCs are much better at $330, and Zavfino Fina OCC at $345 and Zavfino Majestic OCC at $450 should get great consideration for value as well.
I'm DIYing power cables with Neotech, SAEC, Acoustic Revive, Furutech, RAMM Audio, Oyaide (all exotic high end copper used); and those are showing great promise......but won't be able to fully do a comparison/shootout until my audio room is complete later this year.
