I'm trying to decide between a Cambridge Audio 540 +phono preamp (tbd) versus the Marantz PM7001. Either one will feed a seperate amp so power is not a concern. This will be an all analogue TT setup. I'm not sure if the seperate phono preamp route is the way to go? Must have preouts and tone bypass, which both of these appear to have. Anyone have any experience with either of these?
