10' Power Cable for MC275

Good afternoon. New to this hobby.  Does anyone have a suggestion for a 10' power cable for a Mcintosh MC275 mkVI under $300?  I'm an electrician, so can build my own power cable, but am wondering if there's a better solution? Any help would be greatly appreciated. 
I would take a look at the DH Labs Power Plus- excellent cable for that amp and fits your budget as well.  Happy listening!
