Unpossible!
As far as I understand it, Guitar Zero nailed the input transformer. It balances the impedance and does definitely add some color. The output transformer basically takes the signal, splits it in two, reverses the phase on one, and then sends the two out to a balanced input, where the whole process is reversed. That reduces noise picked up by the cable, but it comes at a cost. Plus, the output transformer will add some color.
Also, the power supply is technically a transformer I believe, but theoretically it shouldn't be coloring the audio signal if it is designed properly.
