Well when I said the preamp adds something I did not mean colouring. Without preamp the Wadia sounds great but with the preamp I can set the Wadia to maximum output and maximum volume on the dipswitches. The music then gets more dynamical and open with the preamp. Also the bass is tighter. So in my system it sounds better with the preamp and the Wadia set to maximum output. Also the noise is less then.
