I agree with chipcalzone, this is very clearly a setup issue. If azimuth is off, you will definitely hear more noise from the record than if azimuth is set right, or more right than you have it.
And in my experience, thinness in the sound, to the extent that it's related to your front end, is caused by having the arm a little too high.
Check your arm height again, with the stylus sitting in a record groove, and make sure the arm is exactly parallel to the record surface.
If your tonearm has an adjustment for azimuth, try adjusting that better. Keep in mind that the best sound may not come from a stylus that's perfectly vertical to the record surface.
Tolerances in cartridge manufacturing are larger than we might expect and in many cases cartridges are sold that exceed the manufacturers own tolerance standards.
IOW, you likey have not yet heard what your cartridge actually sounds like, so don't go shopping for a new one until you get to hear the one you already have.
