Will power cable work well as speaker cable?

The reason I'm asking is I'm trying to find oyaide tunami nigo speaker cable in the U.S. & nobody has it. This is supposed to be the same as the tunami power cord with the exception of the ground. VH audio has the power cable. I've made a couple of these using Neotec connectors & am thoroughly impressed with it as power cable. Hearing things I've never heard before in amazing clarity. VH audio (which BTW is a great company) does have Oyaide Across 2000 they sell in bulk for speaker cable. Anyone using that? If so what are your thoughts?
