For those c-hings with big budget, using Nordost Odin as ground wire should give good results. But for small potato like me, I would use spare VDL CS122 speaker cable as ground wire connected to Silver Minimus for trial soon. CS122 is made of silver plated copper wire.
I have been using CS122 as power cord for my Marantz CD player with excellent results. Clarity 提升好多!超爽!窮人恩物
