If you can rip your CDs into a storage (could be a hard drive or a server) and either play directly via connecting to a DAC, or stream via a network, it’ll simplify things.
Transports mattering, or how more expensive devices are better is not the question - a transport is just a mechanical winder with a laser reader which then sends the bits to an external DAC.
A CD player itself is a transport, it just has the DAC within the same case. But step back and think - its more profitable for people within a specific chain if you buy two devices instead of one: manufacturers, distributors and sellers. Are two devices better than one? Could be. Could not be if the one device is made well, if noise is suppressed by ensuring proper shielding.
In certain ways two devices are worse for sure - more materials consumed, more power used, more space needed, more heat produced. Things add up.
