Oyaide Tunami GPX-R: Two for One

I have taken a 2 meter Oyaide Tunami GPX-R Powercord and cut it in two pieces(crazy you say). Ya' like a fox.I took the Tunami GPX-R plug end with the Oyaide P-004 plug and connected it to a Porter-Port 20 Amp outlet that I bought hear on Audiogon years ago,(before outlets were cool).It is housed in a non-magnetic metal-type box that you can buy at the local home improvement store. Yes both ground and drain wires are connected. It works wonders on digital equipment.The other 4ft plus piece with the Oyaide C-004 IEC end was connected to another Oyaide P-004 plug I bought hear on Audiogon as well. However I have the ground cable and bare cooper drain wire removed (floating) on the IEC end. Both ground and drain cables are connected at the Oyaide P-004 plug end. Plugged into my Power amp it is much more open, airey, and dynamic. Has anyone else tried a two for one with the Oyaide Tunami GPX-R Powercord? Or any other Powercord for that matter.
