Been using the stock arm with the Shure cart for a couple of weeks in this new flat, also took out the Slee era v stage as the S500 has its own phono stage and all seems fine. In fact overall sound is better in this flat, room is about same size but with significantly higher ceilings, not bad at all. Just need to get some new cart sorted. Think the nag might be too lush for this new set up, need something more neutral and dynamic maybe. Upto £300, MM only.
