I have a Denon AVR-1513 and where the speaker wire plugs in to the unit, they have the little tab you push up, which then opens the hole to insert the wire into. I have your standard copper/silver speaker wire. I do not recall what gauge it is.............standard speaker wire at the big box hardware stores. i have read a few places that a lot of people have trouble putting any type of connectors on the end of the speaker wire due to the red/black touching each other. can anyone recommend a speaker wire connector that is small enough to not touch the other connectors that are in the surrounding areas?
