Denon DL-103 -- Was it a mistake?

I recently purchased a Denon DL-103 for my Clearaudio Emotion/Satisfy Tonearm combo. I thought it might end up sounded ok, but I'm starting to think it was not a good match. I've only put about 10 hours on it so far, so perhaps it will still smooth out a bit. But the bass seems to get muddy very easily. Can I do some things to improve the sound here?

Thanks
