Wish I had problems like yours ... Tone Publications did a review on Lyra cartridges a while back. Even for the money they command, they are a real value. The review went into more detail and the reviewer was running a VPI Classic II or III I believe. You can shoot Tone an email and Jeff will almost always reply. He has been running Lyra for a while but also lots of other carts. He really knows his stuff and is great to communicate with.
Good luck, I doubt you can go wrong. Love the Mahi's, I nearly bought a set last year but missed out. Grrrrr
