If everything seems about perfect but it sounds ball-less compared to good digital playback, it seems to me that there's something blunting the transients. I agree with Zd542 that you may (probably) need a speed control. You may also have a slightly slipping or stretching belt that needs to be replaced.
TAS had a very favorable review of your very turntable, the Xerxes.20Plus, that extolled its pace and dynamics. However, the test system included Roksan's off-board Reference power supply and their DXP SE phono preamp. Read the TAS review and compare the descrption with your experience. The power supply and phono stage may be worth looking into.
