Transports generally output the same digital signal. Only if they use an ASRC would they not. The ASRC can be tricky to identify when looking at the analog output, but opening the device or getting access to the block diagram would let us know. That said, the interpolator of an ASRC has the tendency to be overloaded with intersample overs tests, showing nasty distorsion and noise all over the place.
I recently had the case, seeing that typical distorsion, and additional tests from the digital outputs confirmed the presence of an ASRC.
