Aleph L vs. Balanced Zen line stage

I'm building an Aleph 4 and need to build a preamp to go with it. I imagine that both would sound good, but does anyone have a recommendation on to which would work better with the amplifier? Also does anyone know of a reasonably priced volume control for a balanced circuit? A shalco or dact would double the price of the preamp enclosure included. I don't know enough to build a volume control similar to somthing in the aleph p, I'm basically limited to attenuators and resistors as far as I know right now. Thanks for the advise.
