@jay73 RE:
So, you literally mean copper wire terminated to spade or banana plugs with the specs that you mentioned?
Exactly - here's the problem with those plates
- they are most probably made of brass or even some copper alloy like Copper Beryllium
- this will not conduct the signal as effectively as pure copper
- if you plug the cables into the HF terminals then the low frequencies are impacted
- if oyu plug the cables into the LF terminals then the high frequencies are impacted
- replacing the plated with pure copper (like Romex) or even better use UP-OCC copper, then you should hear no change regardless of which terminals you pluf the cables into
I had a pair of bi-wire speakers
- I tried bi-wire cables and they worked OK
- then I replaced the plate-jumpers with copper wire and went back to a single cable and it actually sounded better.
- Then a fellow DIYer told me about the 20" jumper - he had researched different lengths a lot and 20" was the optimum length
- I then made UP-OCC copper jumpers from 2 x 18 gauge wire from VH Audio and the speakers had never sounded so good
If you are into DIY tale a look at these cables - they provide excellent results
