Transport or dac which one


I have a set up with 2 transports and 1 dac running one xlr and the other rca. My question is I have a stealth mini digital should I plug both the transports into it or the dac. Does one put more noise in the lines then the other? please help Thanks

I have no way of verifying this, but I think the transport gives off more interference than the DAC reason being it has a laser mechanism. In my system, I separated the DAC and amp from the transport to get the best sound.
