Din to XLR is easy, there are several options on ebay, balanced phono is the way to go. If you need to the SME cable is easily re-terminated with XLR's, any tech should be able to do this for you - if not send it to me and I can do it for you.
I second the Lyra cartridges for the SME, Ortofon is worth looking into also
Good Listening
