Don't you want to have tight contact with copper and casing of banana plug so that it make good contact with speaker or receiver terminal.
Just inserting the copper into the casing with double/triple twist onto itself, IMO doesn't make good contact with the terminal as wire directly inserted into speaker terminal..correct?
As noted, I used the Nak locking plugs with 14AWG wire and I did have to double the copper back on itself. I actually left the leg of the cable pants long enough to insert into the lower section of the plug, so that tightening the bottom screw down on the jacketed portion of the wire holds the wire in quite tight. Then, the I just tightened the upper screw down onto the bare wire (doubled back) so that it made contact, but it wasn't super tight.
I did this with the cables I made for the L/C/R (terminated at wall plates, so both ends done this way), and the front heights, and I also terminated the wires that go into the AVR this way - hooked them all up this weekend and they all work, so I must be getting contact. (The surrounds are flush to the side walls, so just did bare wire in the binding posts)
