experience with TG audio tonearm cable?

looking to upgrade the tonearm cable on my teres/moerch/allaerts/michell delphini pro analog setup. have been using a vdh 501 silver hybrid but i'm reasonably sure that despite extended break-in that it is a limiting factor imparting a "dryish" sound to my LP enjoyment. i'm somewhat remote in location and the cables i'm interested in are not available for audition nor am i close to a metropolitan area. am looking to spend ~$500, and the bob crump designed TG audio cable can be had for just about that. he apparently does not allow audition, and i'm a little leery of buying sound unheard on such a critical link in the system. perspective/advice/alternatives are welcome! have a good one!
