I have Wireworld Elektra 7. It's decent for source and DAC, not so good for the amp. Not exactly responding to the OP's needs but just sharing my experience since somebody above me mentioned about the WW Elektra 7.
I currently do not have any power cords in the $300 price bracket other than the WW Elektra 7. I have two Acrolink power cords which cost 10X more than the Wireworld and the costlier cords surely sound better. Fortunately!
