Well since it's a bit of a wait until we hear about the listening impressions I have a bit of a newbie question:

Is there a recommended way to run speakers in parallel? Should you jam all the wires into one Banana plug or spade? Or should you go spades for one and Bananas for the other? Is that even possible?
