with a 47K load on my supratek Syrah, my denon 103R sounds like ass. Very thin sounding. Pushing this down to 100ohms makes it sound MUCH better. More body. I would look into upgrading turntables before upgrading cartridges. Even a Rega P3 with an Expressimo RB250 with Twl's hifi mod would be a GREAT match for that cartridge. I use the P25 - and it is able to let me just enjoy the music as opposed to analyzing what I don't like about the sound.
