Connecting active subs in stereo and full range stereo speakers to Decware Rachel amp.

Sometime next week my Omega speakers should arrive.  There will be two active subs and two full range speakers.  I want to connect the subs in stereo.  The run from my Decware Rachel amp to the subs will be a bit longer than the run to the full range speakers, and I will be running two-wire cable to each.  From each of the two binding posts on the amp I want to run cable to a sub and to a full range speaker (right channel to right sub and speaker) and left to left.  I would like your advice on how best to connect these cables to the binding posts.  Should I use stackable banana connectors for both, or spades for the full range and bananas above them for the subs, or bare wire for one or the other?  Does it matter?  Also, do you have recommendations for reasonably-priced connectors?
