I'm coming into this a little late, but you might also consider an Exposure X, which should be well within your GBP150 limit, and would match the Marantz nicely. Way back when it was new I had an X, matched with a Marantz and Castle Durham speakers and it was a superb combination. All the oomph and response of Naim without the cost. (I currently own a Nait 5, but am not that sure it's too far ahead of the X!) ~ ~ Dave
