I am blown away by the sonics of the Mogami Platinum guitar cable. It has a superior frequency response and more dynamics compared to any other cable I have played. After spending thousands on all types of pro audio gear, who would have thought that the cable could provide such a sonic upgrade?!
For live playing I do use the Mogami Gold cable ... with comparable sonics to the Platinum, it is a bit more durable and meets the demands of live performance perfectly.
