Get the new Bent Audio Transformer based volume control (Stevens & Billington TX102 transformers, Seiden switch), it is basically a quality passive that doesn't have the impedance matching problems of resistor based passives.
It looks simple to build and the people on audioasylum who have tried TVCs have been very happy (I am still thinking).
