Digital Cable Music Choice


Hello all, I listen to Music Choice from my digital cable box as backround music when I am not playing Cds .
I now use a digital interconnects to watch DD TV but use the analog outputs from the cablebox to listen to music. I was thinking of upgrading the analog interconnects from the cablebox to something like a audioquest Jaguar with DBS , Would this upgrade improve sound or is it a waste of $$ since the signal out of the cable box is limited ?
Thanks~

Background music? Cable box? Waste of money, don't bother with a new cable...

Ok thanks , what would be the best choice using the analog outputs on the cable box ot Digital coax OR toslink fiber ?
IF the digital cable is best would a beter cable here help or just something like Audioquest VDM1 Or the Audioquest optilink 1 would be good enough and again a waste of $$ getting something like Hawk Eye with DBS or Optlink-5
