I've also struggled with the edginess of the 103R. I realigned it several times thinking it wasn't set up properly. I added mass to the tonearm to accommodate its compliance. I damped the plinth to death. I tried several phono stages (Phonomena, Wright WPP100c, WPP200c, EAR 834P). I tried different SUTs (Lundahl and Cinemag). I tried loading at 40 ohms, 100 ohms and 500 ohms. But after all this messing around, I still hear some edginess. What's a fellow to do? yes, yes, take the plastic body off and try an Uwe ebony body. That's not out of the question, but why not try something different altogether?
And that's what I did... I picked up a Grado Reference Sonata. It may not be the last word in high end carts, but you know what? It's so much smoother than the 103R. And there's no fussing with tonearm mass, loading, SUTs, extra ICs. Just get it aligned, sit down and relax. There's something about the Sonata that sounds very nice. The timbre is realistic. The bass is deep. The top end is smooth and free of glare.
I haven't lost hope for the 103, but I'm frustrated. It requires so much tweaking. FWIW, I strongly recommend reading Romy's rant: Denon 103: myths and the reality
