Did you buy this from an authorized dealer? I heard that the grey market ones don't come with a wire. My SME V came with a van den Hul Din to RCA cable. I would contact your local analog dealers and just try different cables. I remember some discussions about an excellent cable by Hovland... That would be one on my audition list.
What are some great tonearm cables for SME IV.Vi
Lyra Lydian Cartridge...SME table. Thanks!
