Txs guys. I´ve read thru prior posts on the Forum, and it seems like there are different versions of the 103 (D, R, Q, etc). I have done some searches on the web, but the places I´ve found that sell Denon cartridges seem to have only one available, with no letter following the number. Any suggestions on where I might find the full line up and, if so, which version might be the best match wth the Ekos?
