Yes, it is possible. I've had good luck bi-wiring with spades at the 1050 (two speaker runs from the same binding post, so two spade lugs on the same post at the 1050).

I haven't used any pre-made bi-wire cables, so don't know what to recommend there, but I've used several different kinds of wire. I've done this with Home Depot wire (bare wire in that case -- do not try to get Monster Cable spades, as the ones I got were too thick to be manageable for bi-wiring), BetterCables premium wire (spades to bananas, which is what's on my center channel right now), and TMC Gold Label.
