Should I use RCA cables or Digital cables for interconnects


I am getting a Marantz SA-KI arriving soon and I was wondering what would be the best way to connect the Ruby to the AV8805 preamp. I have a pair of purist audio RCA cables, An Audioquest carbon Optilink and an Audioquest forest Coax. I was told on my oppo 105d I could bypass the oppo DAC using digital and use the DAC in the preamp. I am not sure why but not using the RCA for the interconnect seemed more pleasing so I switched. My questions are 1) Does using digital bypass the DAC? 2) Which would be the preferable route with the Ruby?
Thank you,

The Ruby has one of the best DACs ever built into a CD player. You should pair it with a much better integrated amp or a preamp/amp combination to unveil its sound potential. A Ruby is an affordable sibling of the 10 flagship series by Marantz. So don't degrade it by using it in an average system. It deserves the best partners you can afford, for example the dedicated Ruby amp. Loudspeakers? High solution preferred because those Ruby machines are hires specialists...
