Modwright Umbilical cords

I own a Modwright Marantz CD/SACD player with the stock umbilical.  Overall its a fine cord but like all things I'm wondering if improvements can be made. I'd be very interested in any feed back people may have on upgrading this cord. I know Modwright recommends the WyWires. Are there any others out there people might recommend? Any feedback is greatly appreciated.

Thanks
