I just ran through my set of test tracks to check the new sound of the VT100 with proper biasing. One is always uncertain in making comparisons without A-B switching but I detected less silkiness in the highs after properly biasing the input tubes. Just a touch more sibilance in female voices. Darn! Maria Callas singing Norma is still quite acceptable; her crescendos are not too brittle. Well not any more when compared to the old tubes. The amp has a slightly more "tubey" sound with the proper biasing; and more than with the old tubes. How does that work? More highs and warmer midrange?
I plan to live with the unit for a while longer to get my money's worth out of the new tubes. I'll probably go for a VS115 by the end of the year.
