This question has a few parts.. Currently I have the bose lifestyle 18 system, and I am selling it luckily to replace with a non bose system. But I sit close to my speakers and I can always hear a fuzzy noise during quiet scenes or when nothing is playing, it's hardly a big deal, but it makes me wonder if I should invest in anything special to go with my new system, which will run off the onkyo sr507. That said, should I get
-Banana plugs? (don't know what they do really? Improve the connection?)
-Power conditioner ( I couldn't imagine spending much on one, but theoretically would it help the fuzzy noise?)
-Hi-Fi speaker wire? I don't need more than 50 feet, but I don't want to spend more than 20 dollars to be honest..
I guess I just want to know what's causing the buzz.. I'm a little afraid that I will get a REALLY loud buzz when I connect my headphones to the new receiver. Do power conditioners help that?
