I am really impressed with this upgrade, as the Burson Audio parts have really taken this unit to a whole new level.
Bass has become deeper & much controlled. Mids are excellently rich & warm, while highs are crystal clear, crisp, and natural. Sound stage has become more open with realistic depths.
Overall presentation is excellent. Thanks also in part to its very good Wolfson DAC. You must upgrade one to believe it.
Best Regards, Ronald
