Still Looking for Amplifier Power cord

Do you have power cord suggestions for a powerful switching amp:
Have a Cary Class D, switching amp 600 watts @8 ohms 1110 watts @4 ohms

Mirage OMD28 speakers:
Frequency Response 25 Hz-20 kHz (+/- 3dB)
Recommended Amplifier Power 50-300 Watts
Impedance 6 Ohms nominal / 3.5 Ohms minimum
Room Efficiency 87 dB

Looking for power cord suggestions for a Class D amp doing duty with Mirage OMD28 which can do 18hz useable bass.

Already tried:
Flavor 4/ Airsine
Pangea AC9
Acrolink/Oyaide

On the cheap, also wondering if anyone tried the inexpensive Wyred4 Sound PC's?

Thanks all.
