Seriously. I have a Pioneer 45tx with Athena speakers all the way around. I currently just have the Athena's hooked up by straight cable (monster cable) with no adapters...or "banana plugs" My question. What exactly are banana plugs...and would I benefit (sound quality) by having them? I believe my system sounds awesome as is...but any tweaks that would increase the sound would be nice. So do I need banana plugs?
