Had this issue years back upgraded with speakon connectors and have used nothing but speakon cables for cabs since thenI was looking through the manual that came with my 1997 Eden D210XLT. It has 1/4" parallel jacks and a Banana Plug (!) input. They highly recommend using the Banana Plug instead of the 1/4" because there is "more surface area". I rarely need- if ever- to use 2 cabinets. The Banana Plug is a PIA if you ask me. Should I replace it with a Neutrik if Eden's claim is valid or is 1/4" just fine?
