Some of my best listening time is late at night when the household is asleep. I play my Ypsilon TVC preamp at very low volumes and feel that I'm missing nothing from the recording. To be fair, the Esoteric front end is a big contributor to this fine low level sound. Although I'm a dealer for both of these products, this is what I hear.
Transformer volume controls
My Doshi has dual stepped transformer volume controls. Do TVCs have the same issues as resistor based controls in terms poor performance when operating the lower end of their range?
