Ambience retrieval & three dimensionality are both improved. The midrange is smoother while remaining very detailed. The amp is more dynamic. It seems to play louder with more dynamic contrasts. Tonal balance is more even across the board but the liquid midrange of the stock machine is retained. Imaging is better defined and the soundstage is larger, both wider and deeper. Bass is improved. It now has fuller weight and more authority, not flubby "one note" bass. The amp sounds more like solid-state in this area. I can also provide a video of amp in action . Automatic biasing eliminates the need to adjust tubes for optimum performance.
