Power cord for Levinson 27.5

any advice on a power cord for my levinson 27.5 amp? do i look for something that is labeled "high current"? thanks.
I would start with a Synergisic Research AC Master Coupler. Used ones are available for around $140. or there abouts. I use them with my new Levinson gear (436 and they sound great) plus you could always resell it easily if you find something better for what you payed.
