From Radio Shack site on their dual-banana conenctor 278-308 "Standard 3/4" spacing. For 12-10 gauge wire, Megacable®. Great fit for speakers with dual banana jacks." Is this a standard? I got one of these to test for my Outlaw 1050. Works fine. But I cannot connect to the Denon AVR-1602 (spacing is wider) I got for my parents for xmas (and am playing with the DPLII right now ) Is this a standard or not? Why does Denon not use 3/4" spacing for their binding posts?
