Lyra cartridges are quite compatible with VPI arms. Go with the Delos or Kleos over the Helikon, which is what I currently own on a JMW 10.5i. Jonathann Carr confirms that either of these models are a step up in performance over the Helikon.
Lyra and VPI Scout
Do Lyra cartridges work well with VPI Scout? I had a Benz H2, sounded horrible, could never get it to track well. I think it is defective and Benz is not handling it. I am currently using a older Benz Glider high output, tracks great, same table and alignment tool, go figure. I have a new phono preamp (Xono) that will accept all kinds of cartridge loads and liked the way a Lyra sounded on my friends old Mission table with a Mechanic tonearm. My table and that one are not in the same league but I wanted to know of anyone else is using Lyra cartridges with the Scout. I was looking at either a Delos or a Helikon. I am not sure about the compatibility with a jmw 9 tonearm.
