I've managed to get hold of a non first gen MT-32 (it has a headphone socket, so hopefully the 33 extra samples in there), but have a number of other sound devices I need to combine it with (AWE32, Dreamcast, SGI O2).
I've been pointed at this :

I especially like the optical out, which will plug nicely into my logitech Z5500.
Would everyone else go with this, or would you be inclined to go with something different?
