I would contact Aesthetix about this.
It might be fairly easy to tap off a pair of connections in the circuit just before the volume control. Hopefully the device connected here has a high enough input impedance to not affect the Io's circuit. You would need to punch out a couple of holes for the new line-level jacks on the back panel. The Io's back panel is already fairly busy as you know so this might be tricky as well.
