Hi. I have bought an Akai AP-X1 from a 2ndhand store lately. Do you know if I would need a preamp for it? If yes are there any specific requirements then? This is a really old turn table and I'm confused with the ground wire. I'm a total dummy about these things so really appreciate any kinds of help on this. In addition do you think thi one could produce decent sound or have I spent useless money (20euros)?
