A/D Convertor/Mic Pre for Nomad JB3??

[Andrew]

Hello all,

I don't post much here, mostly lurk when at work. So here is my first
question.

I'm about to get a JB3 for live recording stuff. And was wondering if
anyone had any recomendations for a A/D convertor/Mic Pre. i've seen
people using the Udirol UA5. Anything else I should look at that has
the optical out the JB3 uses.

Thanks

Andrew
