Sean, tubes *are* as fast as transistors, else vacuum-tube radio circuits could not exist. There are many things that limit bandwidth in tube *designs*, but tubes are not the culprit (check out the risetimes on our website sometime). Soft clipping is caused by space charge effects (a cloud of electrons that occurs near the plate of the tube) which is a phenomena of a tube near saturation. It has nothing to do with bandwidth.
Eldartford, there are transistor amps now that have a 'soft clipping' feature, but clipping distortion is a gross manifestation of the effects that I am referring to. Unfortunately these 'soft clipping' amps still retain the transistor/odd-ordered harmonic signature that the ear detects so easily. This is my own opinion, but I feel this issue of higher/odd ordered harmonics is one of the more important issues that seperates the subjectivists from the objectivists.
