recommendation for rca interconnect for deeper bass for dac to preamp

Hi,

I use a synergistic research galileo rca cable from my preamp to the phono but need another rca cable from preamp to digital.  

the combination of my battery preamp and  chord hugo 2 battery dac is incredibly transparent and great PRAT.  I am thinking a rca interconnect between the two that is known for a strong bass (copper?) would be ideal.  I wish I could use the galileo rca for that too but its a pain to keep switching it from phono to digital player and its too pricey to buy another one (especially since play 80 percent vinyl).

Any suggestion for a used rca IC for under 1K used?

thanks

Michael
