I used a DL-103 on both a Denon DP-62L ( using the S arm) and on a Pioneer PL50 ( early 70's model ) with a higher mass arm. I now have the Denon DL-110 high output mounted on a low end of medium mass arm. Both great cartridges with a variation of the Denon "broadcast" EQ curve.
If you love a big warm midrange, recessed top-end, wide soundstage, and low sensitivity to less than perfect vinyl, the 103 is your cartridge. If you like a more neutral presentation, but with a lively mid-range and a more extended ( but smooth) top-end, then the DL-110 is a good choice, ( and it's darn cheap to purchase ). And it works with MM phono inputs.
I liked the DL-103 for classical ( large orchestra ) and horn based jazz. The DL-110 for small acoustic string ensembles ( jazz, classical, folk, etc ), piano, and rock/electronic.
Good luck with a decision! :scratch2:
