With recent software upgrades the Sony HAPZ1 can now output from its single USB socket, so its possible to hook it up to an external DAC.

The question is this, is it possible to have an external hard drive feeding the Sony and at the same time the Sony feed an external DAC, and if so which USB Hub will suit this task best. My preference is a powered Hub and one I can use my own USB cable to feed the Hub.

Lap tops would be Windows 8 and 7 versions.
