Thom_machris... One of the big differences between the basic VPI 9 inch tonearm and the VPI Signature, is the replacement of Discovery cable to Nordost. The difference is easy to hear in favor of the Nordost. I rewired my Rega arm with Incognito wire, and it was a definite upgrade. I can't tell you if Discovery would be a further upgrade from the Incognito, however, I hear a definite improvement from the Discovery to the Valhalla in the VPI setup.
