Initial impressions are the presentation is more open and clean across the frequency spectrum. The slight change in mid focus from lower to higher range, but overall more detailed. The bottom end is slightly lighter but more accurate. Top-end has opened up quite a lot with more depth and detail. It has enhanced the Totems party trick, which is a huge soundstage. The system now fills the room at any volume.
