With respect to cables, yes, its possible. A lot depends on the design of the transformers. If they are designed to be loaded with the relatively high input impedances that are common in amplifiers today, you will retain the Common Mode Rejection numbers but otherwise the construction of the cable will have a big difference on the sound.
The balanced line system is designed to eliminate cable artifacts! So some output transformers are designed to drive a low impedance (600 ohms being the standard). If the transformer is driving this impedance you insure that the cable is not influencing the sound at all.
