Importance of quality of coax cable feeding a DIP

Got a killer deal on DH Labs D-750 and Just upgraded my better cables silver serpent that was on the output of my DIP feeding my DAC.  The silver serpent was good, but the dh labs is on another Level, stone cold, with no break-in. It's a little thick in the bass right now though.  I still have a silver serpent feeding the DIP from the transport and  I'm wondering if changing that one out to d-750 would be another improvement.  DH labs said it would depend on the quality of the DIP..🤔 The reclocked signal over the d-750 is fantastic to these ears. It goes extremely well with the SR UEF BLACK power cord I also just got for the DAC.  Together, the synergize very well. For the price paid, I haven't a single complaint. My system has never sounded better.   How important is the cable feeding the DIP?  I would think it would be even MORE important than the cable feeding the DAC, No?
