Marantz 1060 Speaker Terminal Gold Plated 5-Way Banana Jack Binding Posts.

The lettering and finish looks a bit better in person than it does in these very detailed close up pictures though I won't claim it's as crisp as the lettering it covers up on the Marantz. Accepts up to 8 AWG wire, banana plugs, forks, spades, and speaker pins.
