xd versions are very very incrementally altered over just prior gen harbeths
That’s useful. From my observation, the popular XD models that get the most attention are the C7ES3 and M30. The other models don’t get much interest, and the P3ESR XD is a mixed bag. It appears that several P3ESR owners who switched to the P3ESR XD are having difficulty adapting to the bright treble in the new model.
