Let me preface this question by saying I live in Japan and so don't usually understand everything electronics store staff tell me. I host monthly parties at a small club. For the music, I connect my iPod directly into their amp using RCA plugs. When I was buying the cable the guy at the store told me I should look into getting the iPod dock because it would boost my signal. So my question is, will connecting the cables to a dock improve my sound and/or volume? And is it a noticable difference? Also other companies make docks with speakers. How about those?
