Power Cable for Line Magnetic LM518 IA -- 22 Watt SET

I've been using an old Virtual Dynamics Power 3 on this amp since I've had it and need an upgrade.  I do not have a lot of experience with power cables.  My budget is $750-$1250 and I'd prefer to purchase used.  I'm installing a dedicated 20A line for the audio system and am installing 2 Furutech GTX -DR NCF outlets with matching covers and mounting plates.  I'll be looking into power conditioning/distribution as well.  Thus far, I'm wide open on that but the Shindo Mr. T is first on my list, although I'd prefer to have 8 outlets rather than 6 if possible.

If possible, I'd like a cable that can help improve soundstaging and imaging.
