reading the review by audiotweaks on the bent audio site www.bentaudio.com will give you an idea of the requirements for passive volume control,the resistor formats series,shunt and ladder, and the transformer alternative.www.audiosynthesis.co.uk description of the passion 8,also lays out the ideal requirements for a resistor type.I have both a synthesis and a bent noh both sound wonderfull but my system at present suits the noh which is available with either copper or silver tx102,s a chat with john chapman about your system would help to choose the correct type of transformer for you.If you do choose a resistor type at least look at audiosynthesis they are the uk distributers for vishay bulk foil reistors,neutrik connectors+they also manufacture high quality silver cables and all of their products feature these components.Also their fit and finish is of the highest standard.
