Each of my speaker cables are currently bi-wired on the speaker end (4 plugs) but combined at the amplifier end (2 plugs). That was because my old amplifier only had one set of speaker terminals. Now that my amplifier has two sets of speaker terminals, would it be worthwhile for me to convert the speaker cables at the amplifier end so that it's truly bi-wired (ie. 4 to 4, rather than 2 to 4)?
