I'm soret of new to the vinyl game (three years) but I think you shoudl start woith a new cart first. Nothign wrong with shure, but I think he Xerxes is a solid table and it's probably time for a new cart anyways. I recently purchased a Scout from VPI. Eventually I'll upgrade to an Aries, but for now the Scout is fine. In terms of your musical tastes I think the Aries/Scout and Clearaudio woudl be the clearest choices in terms of neutrality and tone. The Nottingham was more musical and had a fatter darker sound but I prefeed the VPI for my analog tastes. I commend you on your system choice though, I have an all Blue Circle system myself! One of these days I'll pick up a BC23, but for now the Black cube is doing quite well. Try a new cart and maybe you'l luck out and be happy~
