Did you buy new or used? New their warranty is good and they support it. I have an XMC-1 refurbished, enjoy the sound and the flexibility. They also have a forum, join and read the user comments.
Many of us enjoy helping other members in their area. There could be another member in your area that might help with your cartridge upgrade or arm set-up. Where are you? Maybe we'll find a volunteer. Also I found my AT OC 9 here, in Bartertown. Cartridges come up frequently.
