I am aware that a transport dosen't have a filter but a dac does and
thats where the digital signal goes to. To perform at its optimum it
needs a clean digital signal. On a scope you can see how clean the
signal is.

I do not know what experience you have of listening to CD transports
but I can assure you they sound different and there must be reasons
for that.

I assure you that if you do naive listening tests, everything sounds
different, even two identical CD players.
