I second the concept of avoiding a linestage. "Use the (phono pre-amp's) gain pots for volume control" is absolutely right.
But usually we have more than one source, and we don't want to shift interconnect cables. We would like a selector and a centralized volume control.
So, even better, remove the Wright's inexpensive gain pots completely, then run it into a high-end passive pre-amp, such as the Bent Audio or Music First Audio transformer based pre-amps. Then run CD players, tuners and everything else with no line-stage also.
