I'm looking for the right cartridge for my Airtangent/Nordic concept which replaces my trusty LP12. The LP12 is fully upgraded, and includes Ekos arm, lingo and linto with akriv catridge. I'm having a bit of trouble getting the Airtangent going, so if anyone has experience to share I'd appreciate it. I'm looking for a V.D.Hull Grasshopper, Lyra, or Koetsu or equivalent for the Airtangent.
