Jmcgrogan2 beat me to it. The tweaks and ads from Coconut Audio are the only ones coming to my mind.
I have enjoyed some the tweaks that Elizabeth has mentioned. I did a combination of them. It was speaker wire with ferrite cores and a 6 volt lantern battery with a 1000u cap across the top. Ugly but the results sounded pretty nice in one system I had them in.
