Mceljo,
I think your approach may have some major flaws. I am not a fan of toslink. Regardless of my opinion it is a fact that toslink and S/PDIF outputs are different beasts and not treated equally by manufacturers. Sometimes toslink is not much more than an afterthought.
You need to find out if either CD player manufacturer or the DAC manufacturer recommend a preferred output/input. I doubt if the CDP manufacturers make any recommendation for digital out but the DAC manufacturer may make a recommendation for a preferred input.
If you want to compare sources you have to make sure everything else in the chain is up to the task. I think you are already in trouble with your choice of toslink. At least that is my experience with inexpensive toslink cables on equipment where S/PDIF or AES/EBU were designed to be the primary in/outs.
