black cat 110 digit aes/ebu vs snake river boomslang aes/ebu vs kimber orchid aes/ebu

anybody compare these cables, I am using now the acoustic zen mc2 aes/ebu and would like to have more bottom end. my midrange and top end is great, and I am  happy with the sound stage but would like more bottom end. I have been using this cable az mc2 for at least a dozen years and I think I need a change. my transport is the new project rs2 and the dac is a bryston bda-2 any opinions would help thanks kully
