Hello, I'm moving in to a new place and was looking at getting a record player which has no phono preamp built in. I have a set of powered speakers (M-Audio AV30's) from my previous studio setup. Each speaker has a 10 watt amp in but I'm not sure if I'll need a separate phono preamp still. There is a left and right RCA connection on the speaker where the power cable connects. If I do need one I have a tiny budget and was looking at a Beringer pp400 any recommendations?
