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?

Update:
I replaced the power cable with 12ga oyaide speaker wire. Now using the power cable as it was designed to be used. Although it worked well as speaker cable I couldn't get past the fact that it wasn't designed for it. That and in my experience I get more bang for the buck (sound improvement wise) with power cables in my system than speaker cables. The beauty of this upgrade is that I now have Oyaide Tunami power cables going to all the electronics (except the TT motor) associated with the analog portion of my system. I will be replacing the IC's with Oyaide as well as soon as funds allow. There is simply something very right about this wire.
