Clearaudio Emotion lacks dynamics

I just received a used Clearaudio Emotion with Virtuoso cart. I've realigned the cartridge using the provided alignment card, and that appears to be normal (alignment and overhang). I've used a stylus pressure gauge to ensure that I'm tracking around 2 grams (the suggested tracking for the Virtuoso Wood). However, the seems to be lacking bass and dynamics. Everything sounds flat, dynamically. One thing I have noticed is that the back end of the tone arm (the end with the counterweight) seems to be LOWER than the end with the cartridge while playing albums. Could this be the source of my problem? This is the one thing I haven't tried to adjust so far, mainly because it seems like it's the most difficult to do.

Any advice would be appreciated.

Thanks
