@dvdboulet, Although the Equi=Core 50, 150 and 300 are good stand-alone power cords I don't recommend using them with the 1200 or 1800.
On the 1200 or 1800, I would recommend the power cord of your choice that's made for a power conditioner or large watt product.
At the end of this review: http://www.audiophilia.com/reviews/2017/6/4/core-power-technologies-equicore-1800-power-conditioner there is mention of a red and black power cord that came with the reviewers 1800 unit. I don't know if that power cord still comes with the 1800, however, I do have two of them that came with a Deep Core that I was supposed to beta test but UPS delivered the unit damaged. I can attest that in my opinion they are good power cords and compete with power cords costing $1000. Mark does sell those power cords at a very reasonable price, however, I can't locate that information at the present time but it would not surprise me if someone else can post a link for you.
If you or anyone else reading this is interested in a spacific power cord to use for the 1200 or 1800 or from the balanced power unit to your compoients fell free to send me a PM and be sure to let me know a price range. I've tesred many power cords.
